 # Mol*
 
-The goal of **Mol\*** (*/'mol-star/*) is to provide a technology stack that will serve as a basis for the next-generation data delivery and analysis tools for macromolecular structure data. This is a collaboration between PDBe and RCSB PDB teams and the development will be open-source and available to anyone who wants to use it for developing visualization tools for macromolecular structure data available from [PDB](https://www.wwpdb.org/) and other institutions.
+The goal of **Mol\*** (*/'mol-star/*) is to provide a technology stack that serves as a basis for the next-generation data delivery and analysis tools for (not only) macromolecular structure data.

-The core of Mol* currently consists of these modules (see under `src/`):
+- The [pdbe-molstar](https://github.com/molstar/pdbe-molstar) library is the Mol* implementation used by EMBL-EBI data resources such as [PDBe](https://pdbe.org/), [PDBe-KB](https://pdbe-kb.org/) and [AlphaFold DB](https://alphafold.ebi.ac.uk/). This implementation can be used as a JS plugin and a Web component and supports property/attribute-based easy customisation. It provides helper methods to facilitate programmatic interactions between the web application and the 3D viewer. It also provides a superposition view for overlaying all the observed ligand molecules on representative protein conformations.
+
+- [rcsb-molstar](https://github.com/molstar/rcsb-molstar) is the Mol* plugin used by [RCSB PDB](https://www.rcsb.org). The project provides additional presets for the visualization of structure alignments and structure motifs such as ligand binding sites. Furthermore, [rcsb-molstar](https://github.com/molstar/rcsb-molstar) allows to interactively add or hide of (parts of) chains, as seen in the [3D Protein Feature View](https://www.rcsb.org/3d-sequence/4hhb).

+The files in this directory are used for deploying the Mol* Viewer as a PWA (Progressive Web App) at https://molstar.org/viewer/. They may serve as an example for creating your own PWA but wont work as-is. See `/script/deploy.js` for where these files are copied and how they are transformed during deployment.
+
+
+## PWA features
+
+- The Service Worker will cache static resources so the Viewer can be used without internet access. This works without installing, i.e., also in Firefox.
+- Once installed, file types listed in the Manifest can be opened from, e.g., the Windows File Explorer.
+
+
+## Notes for development
+
+In Chrome you can see a list of installed PWAs at chrome://apps/. A right-click opens a menu with an option uninstall.
+
+The Chrome Dev Tools have a section 'Application' to inspect and manage PWA aspects like the Manifest and Service Workers.

+# Convert CIF to BinaryCIF
+BinaryCIF is an efficient, binary flavor of the CIF format. See [specification](https://github.com/molstar/BinaryCIF) and [publication](https://doi.org/10.1371/journal.pcbi.1008247) for further details.
+
+This script reads data in CIF format and converts it lossless to a BinaryCIF file that can be read by Mol* or other 
+applications.
+
+## Example
+```sh
+node lib/commonjs/cli/cif2bcif/index.js file.cif file.bcif
+```
+
+## Usage
+| Argument | Description |
+| --- | --- |
+| `src` | Source CIF to convert (can be gzipped) |
+| `out` | Generated BinaryCIF output path |
+| `-c` | Path to optional config file |
+| `-f` | Path to optional filter file |
+
+```sh
+index.js [-h] [-c CONFIG] [-f FILTER] src out
+```
+
+### Config file
+Controls how certain columns will be encoded. This is a JSON array of instructions:
+```ts
+interface EncodingStrategyHint {
+    categoryName: string,
+    columnName: string,
+    encoding: 'pack' | 'rle' | 'delta' | 'delta-rle',
+    precision?: number
+}
+```
+Identify a particular CIF columns by its name and override the encoding by Integer Packing, Run-Length Encoding, Delta 
+Encoding, or Delta & Run-Length Encoding. You can optionally control the precision if dealing with float values.
+
+### Filter file
+Specifies which categories and columns will be written. This is a plain text file, each line represents one entry. 
+You can specify explicitly which categories or columns to include by adding `category_name` or 
+`category_name.field_name`. You can also choose to ignore some categories or columns by adding `!category_name` or 
+`!category_name.field_name`.

+# Model Server
+
+Provides access to molecular 1D, 2D, and 3D (sub-)structure models of molecules. Substructures are described by the 
+mol-script (MolQL) language. It has the ability to include additional data to mmCIF “on the fly”, e.g. integrate 
+primary PDB archival data from [Chemical Component Dictionary (CCD)](https://www.wwpdb.org/data/ccd), 
+[Protonation Variants Companion Dictionary (PVCD)](https://www.wwpdb.org/data/ccd) and 
+[Biologically Interesting moleculeReference Dictionary (BIRD)](https://www.wwpdb.org/data/bird). 
+
+## Example
+```sh
+node lib/commonjs/servers/model/server --sourceMap pdb-bcif '/opt/data/bcif/${id}.bcif'
+```
+
+## Usage
+| Argument | Description |
+| --- | --- |
+| `--version`, `-v` | Show program's version number and exit. |
+| `--cfg` | JSON config file path. If a property is not specified, cmd line param/OS variable/default value are used. |
+| `--printCfg` | Print current config for validation and exit. |
+| `--cfgTemplate` | Prints default JSON config template to be modified and exit. |
+| `--apiPrefix` | Specify the prefix of the API, i.e. <host>/<apiPrefix>/<API queries> |
+| `--defaultPort` | Specify the port the server is running on |
+| `--cacheMaxSizeInBytes` | Read structures are cached, this specifies the cache size, 0 for off. |
+| `--cacheEntryTimeoutMs` | Specify in ms how long to keep entries in cache. |
+| `--requestTimeoutMs` | The maximum number of ms the server spends on a request. |
+| `--queryTimeoutMs` | The maximum time the server dedicates to executing a query in ms. Does not include the time it takes to read and export the data. |
+| `--shutdownTimeoutMinutes` | Server will shut down after this amount of minutes, 0 for off. |
+| `--shutdownTimeoutVarianceMinutes` | Modifies the shutdown timer by +/- `timeoutVarianceMinutes` (to avoid multiple instances shutting at the same time) |
+| `--maxQueryManyQueries` | Maximum number of queries allowed by the query-many at a time |
+| `--defaultSource` | modifies which 'sourceMap' source to use by default |
+| `--sourceMap` | Map `id`s for a `source` to a file path. Example: `pdb-bcif '../../data/bcif/${id}.bcif'` - JS expressions can be used inside `${}`, e.g. `${id.substr(1, 2)}/${id}.mdb` Can be specified multiple times. The `SOURCE` variable (e.g. `pdb-bcif`) is arbitrary and depends on how you plan to use the server. Supported formats: cif, bcif, cif.gz, bcif.gz |
+| `--sourceMapUrl` | Same as `--sourceMap` but for URL. `--sourceMapUrl src url format` Example: `pdb-cif 'https://www.ebi.ac.uk/pdbe/entry-files/download/${id}_updated.cif' cif` Supported formats: cif, bcif, cif.gz, bcif.gz. Supported protocols: http://, https://, gs:// |

+### Production Use
+In production, it is required to use a service that will keep the server running, such as [forever.js](https://github.com/foreverjs/forever).
+
+### Memory Issues
+Sometimes nodejs might run into problems with memory. This is usually resolved by adding the ``--max-old-space-size=8192`` parameter.
+
+### Preprocessor Example
+The preprocessor application allows addiing custom data to CIF files and/or 
+[convert CIF to BinaryCIF](./convert-to-bcif.md).
+```sh
+node lib/commonjs/servers/model/preprocess
+```
+
+### Preprocessor Usage
+| Argument | Description |
+| --- | --- |
+| `--input`, `-i` | Input filename |
+| `--outCIF`, `-oc` | Output CIF filename |
+| `--outBCIF`, `-ob` | Output BinaryCIF filename |
+| `--cfg`, `-c` | Config file path |
+| `--folderIn`, `-fin` | Convert folder |
+| `--folderOutCIF`, `-foc` | Convert folder text output |
+| `--folderOutBCIF`, `-fob` | Convert folder binary output |
+| `--folderNumProcesses`, `-fp` | Convert folder number processes |
+
+Example cfg.json:
+```ts                       
+{ 
+    "numProcesses": 1, 
+    "customProperties": { 
+        "sources": [ "wwpdb" ], 
+        "params": { 
+            "wwPDB": { 
+                "chemCompBondTablePath": "./build/data/ccb.bcif"
+            }
+        }
+    }
+}
+```
+
+### Local Mode
+The server can be run in local/file based mode using
+```sh
+node lib/commonjs/servers/model/query
+```
+
+### Custom Properties
+This feature is still in development.
+
+It is possible to provide property descriptors that transform data to internal representation and define how it should 
+be exported into one or mode CIF categories. Examples of this are located in the ``mol-model-props`` module and are 
+linked to the server in the config and ``servers/model/properties``.
+
+## From NPM
+
+```
+npm install --production molstar
+cd ./model-server 
+```
+
+(or ``node node_modules\.bin\model-server`` in Windows).
+
+The NPM package contains all the tools mentioned in the previous sections as "binaries":
+
+- ``model-server``
+- ``model-server-query``
+- ``model-server-preprocess``

 This document provides a high level overview of how the DensityServer works.

+# VolumeServer
+
+## What is VolumeServer
+
+Provides near-instantaneous access to volumetric data including density maps (for instance, from X-ray crystallography 
+or cryo-electron microscopy experiments), spatial distribution data, output from electrostatic calculations. It works by
+utilizing adaptive downsampling (similar to how Google Earth works). 
+
+It uses the text based CIF and BinaryCIF formats to deliver the data to the client. 
+
+For quick info about the benefits of using the server, check out the [examples](examples.md).
+
+## Installing and Running
+
+Requires nodejs 8+.
+
+### From GitHub
+
+```
+git clone https://github.com/molstar/molstar
+npm install
+```
+
+Afterwards, build the project source:
+
+```
+npm run build:lib
+```
+
+and run the server by 
+
+```
+node lib/commonjs/servers/volume/server
+```
+
+### From NPM
+
+```
+npm install --production molstar
+./volume-server 
+```
+
+(or ``node node_modules\.bin\volume-server`` in Windows).
+
+The NPM package contains all the tools mentioned here as "binaries":
+
+- ``volume-server``
+- ``volume-server-pack``
+- ``volume-server-query``
+
+
+#### Production use
+
+In production it is required to use a service that will keep the server running, such as [forever.js](https://github.com/foreverjs/forever).
+
+
+#### Memory issues
+
+Sometimes nodejs might run into problems with memory. This is usually resolved by adding the ``--max-old-space-size=8192`` parameter.
+
+
+### Preparing the Data
+
+For the server to work, CCP4/MAP (models 0, 1, 2 are supported) input data need to be converted into a custom block format. 
+To achieve this, use the ``pack`` application (``node lib/commonjs/servers/volume/pack`` or ``volume-server-pack`` binary from the NPM package).
+
+### Local Mode
+
+The program  ``lib/commonjs/servers/volume/query`` (``volume-server-query`` in NPM package) can be used to query the data without running a http server.
+
+### Navigating the Source Code
+
+The source code is split into 2 mains parts: ``pack`` and ``server``:
+
+- The ``pack`` part provides the means of converting CCP4 files into the internal block format.
+- The ``server`` includes
+  - ``query``: the main part of the server that handles a query. ``execute.ts`` is the "entry point".
+  - ``algebra``: linear, "coordinate", and "box" algebra provides the means for calculations necessary to concent a user query into a menaningful response.
+  - API wrapper that handles the requests.
+
+## Consuming the Data 
+
+
+The data can be consumed in any (modern) browser using the [ciftools library](https://github.com/molstar/ciftools) (or any other piece of code that can read text or binary CIF).
+
+The [Data Format](./response-data-format.md) document gives a detailed description of the server response format.
+
+As a reference/example of the server usage is available in Mol* ``mol-plugin`` module.
+
+## Hosting the server
+
+### Example
+
+```sh
+node lib/commonjs/servers/volume/server --idMap x-ray '/opt/data/xray/${id}.mdb'
+```
+
+### Usage
+| Argument= | Description |
+| --- | --- |
+| `--cfg` | JSON config file path. If a property is not specified, cmd line param/OS variable/default value are used. |
+| `--printCfg` | Print current config for validation and exit. |
+| `--cfgTemplate` | Prints default JSON config template to be modified and exit. |
+| `--apiPrefix` | Specify the prefix of the API, i.e. <host>/<apiPrefix>/<API queries> |
+| `--defaultPort` | Specify the port the server is running on |
+| `--shutdownTimeoutMinutes` | Server will shut down after this amount of minutes, 0 for off. |
+| `--shutdownTimeoutVarianceMinutes` | Modifies the shutdown timer by +/- `timeoutVarianceMinutes` (to avoid multiple instances shutting at the same time) |
+| `--idMap` | Map `id`s for a `type` to a file path. Example: `x-ray '../../data/mdb/xray/${id}-ccp4.mdb'` - JS expressions can be used inside `${}`, e.g. `${id.substr(1, 2)}/${id}.mdb` - Can be specified multiple times. - The `TYPE` variable (e.g. `x-ray`) is arbitrary and depends on how you plan to use the server. By default, Mol* Viewer uses `x-ray` and `em`, but any particular use case may vary. - If using URL, it can be http://, https://, gs:// or file:// protocol.|
+| `--maxRequestBlockCount` | Maximum number of blocks that could be read in 1 query. This is somewhat tied to the ``maxOutputSizeInVoxelCountByPrecisionLevel`` in that the `<maximum number of voxel> = maxRequestBlockCount * <block size>^3`. The default block size is 96 which corresponds to 28,311,552 voxels with 32 max blocks. |
+| `--maxFractionalBoxVolume` | The maximum fractional volume of the query box (to prevent queries that are too big). |
+| `--maxOutputSizeInVoxelCountByPrecisionLevel` | What is the (approximate) maximum desired size in voxel count by precision level - Rule of thumb: `<response gzipped size>` in `[<voxel count> / 8, <voxel count> / 4]`. The maximum number of voxels is tied to maxRequestBlockCount. |

+    <h1>Integration of Mol* with MolViewSpec Extension</h1>
+    <p>
+        This page demonstrates several methods to integrate Mol* Viewer in a web page and use MolViewSpec functionality.
+        See the source HTML to see the actual code.
+    </p>
+
+
+    <h2>Method 1: Get MVS view from a server and pass to the viewer</h2>
+    <p>
+        The recommended method is to serve the MVS view files by your server (either as static files or generated by the
+        server on-demand) and call the <code>loadMvsFromUrl</code> method to retrieve and load them.
+        This example uses a MVS view file from the address specified in the <code>sourceUrl</code> variable.
+        If the MVS view file contains relative references, they will be resolved as relative to <code>sourceUrl</code>.
+    </p>
+
+    <div id="viewer1" style="position: relative; width: 500px; height: 500px;"></div>
+    <script>
+        const sourceUrl = 'https://raw.githubusercontent.com/molstar/molstar/master/examples/mvs/1h9t_domain_labels.mvsj';
+        molstar.Viewer.create('viewer1', { layoutIsExpanded: false, layoutShowControls: false })
+            .then(viewer => viewer.loadMvsFromUrl(sourceUrl, 'mvsj'));
+    </script>
+
+
+    <p>
+        A variation of this method uses <code>molstar.PluginExtensions.mvs.loadMVS</code> instead of
+        <code>loadMvsFromUrl</code> and allows replacing the MVS view after it has been loaded.
+    </p>
+
+    <div id="viewer1b" style="position: relative; width: 500px; height: 500px;"></div>
+    <button onclick="loadView1();">View 1</button>
+    <button onclick="loadView2();">View 2</button>
+    <script>
+        let theViewer;
+        function load(viewer, url, replace) {
+            fetch(url)
+                .then(response => response.text())
+                .then(text => molstar.PluginExtensions.mvs.MVSData.fromMVSJ(text))
+                .then(mvsData => molstar.PluginExtensions.mvs.loadMVS(viewer.plugin, mvsData, { sourceUrl: url, sanityChecks: true, replaceExisting: replace }));
+        }
+        function loadView1() {
+            load(theViewer, 'https://raw.githubusercontent.com/molstar/molstar/master/examples/mvs/1cbs.mvsj', true);
+        }
+        function loadView2() {
+            load(theViewer, 'https://raw.githubusercontent.com/molstar/molstar/master/examples/mvs/1cbs-focus.mvsj', true);
+        }
+        molstar.Viewer.create('viewer1b', { layoutIsExpanded: false, layoutShowControls: false })
+            .then(viewer => {
+                theViewer = viewer;
+                loadView1();
+            });
+    </script>
+
+
+    <h2>Method 2: Construct MVS view on frontend and pass to the viewer</h2>
+    <p>
+        Another option is to utilize the MVS builder provided by the extension to build the view on frontend and then
+        pass it to the viewer. This example builds the view in plain JavaScript, directly in a &lt;script&gt; tag in
+        HTML. However, for a better developer experience consider writing the code in TypeScript.
+        If the built MVS view contains relative references, they will be resolved as relative to the URL of this HTML
+        page.
+    </p>
+
+    <div id="viewer2" style="position: relative; width: 500px; height: 500px;"></div>
+    <script>
+        // Build an ad-hoc MVS view
+        const builder = molstar.PluginExtensions.mvs.MVSData.createBuilder();
+        const structure = builder
+            .download({ url: 'https://www.ebi.ac.uk/pdbe/entry-files/1cbs.bcif' })
+            .parse({ format: 'bcif' })
+            .modelStructure({});
+        structure
+            .component({ selector: 'polymer' })
+            .representation({ type: 'cartoon' })
+            .color({ color: 'green' });
+        structure
+            .component({ selector: 'ligand' })
+            .label({ text: 'Retinoic acid' })
+            .focus({})
+            .representation({ type: 'ball_and_stick' })
+            .color({ color: '#cc3399' });
+        const mvsData = builder.getState();
+
+        // Initialize viewer and load MVSJ
+        const mvsj = molstar.PluginExtensions.mvs.MVSData.toMVSJ(mvsData);
+        molstar.Viewer.create('viewer2', { layoutIsExpanded: false, layoutShowControls: false })
+            .then(viewer => viewer.loadMvsData(mvsj, 'mvsj'));
+
+        // // Alternative initialization and loading (avoids encoding and again decoding the data, allows changing the view by using `replaceExisting: true`):
+        // molstar.Viewer.create('viewer2', { layoutIsExpanded: false, layoutShowControls: false })
+        //     .then(viewer => molstar.PluginExtensions.mvs.loadMVS(viewer.plugin, mvsData, { sourceUrl: undefined, sanityChecks: true, replaceExisting: false }));
+    </script>
+
+
+    <p>
+        Again, there is variation with using <code>molstar.PluginExtensions.mvs.loadMVS</code> instead of
+        <code>loadMvsData</code>.

+# wwPDB StructConn extension
+
+The STRUCT_CONN category in the mmCIF file format contains details about the connections between portions of the structure. These can be hydrogen bonds, salt bridges, disulfide bridges and so on (see more at <https://mmcif.wwpdb.org/dictionaries/mmcif_pdbx_v40.dic/Categories/struct_conn.html>).
+
+**wwPDB StructConn extension** in Mol* provides functionality to retrieve and visualize these connections.
+
+The extension exposes three functions, located in `src/extensions/wwpdb/struct-conn/index.ts`. 
+
+- `getStructConns` - to retrieve struct_conn records from a loaded structure
+- `inspectStructConn` - to visualize a struct_conn
+- `clearStructConnInspections` - to remove visulizations created by `inspectStructConn`
+
+
+## Example 1

+```
+
+The PDB ID (`'5elb'`) can be replaced be `undefined`, in which case the functions will apply to the first loaded structure.
+
+
+## Example 2
+
+This is a more elaborated example, which automatically loads `5elb` (or any PDB entry given in the URL after `?pdb=`), retrieves the list of struct_conns, and creates a button for each struct_conn. 
+
+Be aware that some of the struct_conns may be present in the deposited model but not in the preferred assembly (default view). The presented example will raise a dialog window with error message in such cases, e.g. `disulf6` in entry `5elb`.

+# Tunnel Visualization Extension
+This documentation outlines the usage of the Mol* extension for visualizing tunnels in molecular structures. The extension integrates with Mol* to render 3D representations of tunnels using specified data sources and properties.
+
+The extension is a key component in ChannelsDB (https://channelsdb2.biodata.ceitec.cz/), enabling users to visualize tunnels within molecules directly from the database. While it is used with ChannelsDB, users can also input their own data or connect to different databases, ensuring versatility across various research environments.
+
+## Data Types
+The primary data types involved in tunnel visualization are:
+
+### Tunnel
+A Tunnel object contains the actual tunnel data necessary for visualization. It consists of:
+
+- `data`: An array of `Profile` objects that describe the tunnel at various points.
+- `props`: Properties such as the tunnel's type, ID, and optional labels or descriptions.
+
+### Profile
+A `Profile` object in a `Tunnel` holds detailed geometric and physical properties of a tunnel at specific points along its length. These properties include:
+
+- `Charge`: The electric charge at a specific point in the tunnel.
+- `Radius`: The overall radius of the tunnel at this point.
+- `FreeRadius`: The radius of the tunnel not obstructed by any molecular elements.
+- `T`: Temperature factor or a similar property related to the point.
+- `Distance`: Distance along the tunnel's path from the start.
+- `X`, `Y`, `Z`: Coordinates of the point in 3D space.
+
+These profiles are crucial for understanding the physical and chemical environment inside the tunnel, allowing for detailed analysis and visualization.
+
+Example:
+```json
+"Profile": [
+    {
+        "Radius": 1.49,
+        "FreeRadius": 1.49,
+        "T": 0,
+        "Distance": 0,
+        "X": -19.152,
+        "Y": -22.654,
+        "Z": -13.034,
+        "Charge": 0
+    },
+    {
+        "Radius": 1.524,
+        "FreeRadius": 1.524,
+        "T": 0.00625,
+        "Distance": 0.087,
+        "X": -19.162,
+        "Y": -22.596,
+        "Z": -12.969,
+        "Charge": 0
+    },
+    {
+        "Radius": 1.56,
+        "FreeRadius": 1.56,
+        "T": 0.0125,
+        "Distance": 0.174,
+        "X": -19.171,
+        "Y": -22.539,
+        "Z": -12.905,
+        "Charge": 0
+    }
+]
+```
+## Transformers Usage
+The extension uses several transformations to process and visualize tunnel data:
+
+### Tunnels Data Transformer
+- `Purpose`: Converts a collection of Tunnel data into a state object.
+- `Usage`:
+    ```typescript
+    update.toRoot().apply(TunnelsFromRawData, { data: tunnels });
+    ```
+
+### Tunnel Data Provider
+- `Purpose`: Converts single Tunnel data into a state object for individual processing.
+- `Usage`:
+    ```typescript
+    update.toRoot().apply(TunnelFromRawData, {
+        data: {
+            data: tunnel.Profile,
+            props: { id: tunnel.Id, type: tunnel.Type }
+        }
+    });
+    ```
+
+### Tunnel Shape Provider
+- `Purpose`: Provides the shapes for rendering the tunnel based on WebGL context and shape parameters.
+- `Usage`:
+    ```typescript
+    update.apply(TunnelShapeProvider, {
+        webgl,
+    }).apply(StateTransforms.Representation.ShapeRepresentation3D);
+    ```
+
+## Visualization Examples
+To help users understand how to use these transformations in practice, include detailed examples:
+
+### Visualizing Multiple Tunnels
+This example (see `src/extensions/sb-ncbr/tunnels/examples.ts#L19`) demonstrates how to visualize multiple tunnels from a fetched dataset.
+```typescript
+update.toRoot()
+        .apply(TunnelsFromRawData, { data: tunnels })
+        .apply(SelectTunnel)
+        .apply(TunnelShapeProvider, { webgl })
+        .apply(StateTransforms.Representation.ShapeRepresentation3D);
+```
+
+### Visualizing a Single Tunnel
+This example (see `src/extensions/sb-ncbr/tunnels/examples.ts#L46`) shows how to visualize a single tunnel.
+```typescript
+update.toRoot()
+        .apply(TunnelFromRawData, {
+            data: {
+                data: tunnel.Profile,
+                props: { id: tunnel.Id, type: tunnel.Type }
+            }
+        })
+        .apply(TunnelShapeProvider, { webgl })
+        .apply(StateTransforms.Representation.ShapeRepresentation3D);

+# Exporting components
+
+Export components data can be useful to reproduce the same view in a different visualization software.

+# Building a Custom Library
+
+This page goes over creating a custom Mol\* based library usable inside a `<script>` tag in an HTML page using the `esbuild` tool.
+
+## Setup
+
+- Create a new npm/yarn package
+- Install `molstar` and `esbuild` packages
+
+```
+mkdir molstar-lib
+cd molstar-lib
+npm init
+npm install molstar
+npm install esbuild --save-dev
+```
+
+## Example Library Code
+
+Create new file `src/index.ts` (or `.js` if you don't want to use TypeScript):
+
+```ts
+import { DefaultPluginSpec, PluginSpec } from 'molstar/lib/mol-plugin/spec';
+import { PluginContext } from 'molstar/lib/mol-plugin/context';
+
+export async function initViewer(element: string | HTMLDivElement, options?: { spec?: PluginSpec }) {
+    const parent = typeof element === 'string' ? document.getElementById(element)! as HTMLDivElement : element;
+    const canvas = document.createElement('canvas') as HTMLCanvasElement;
+    parent.appendChild(canvas);
+
+    const spec = options?.spec ?? DefaultPluginSpec();
+
+    const plugin = new PluginContext(spec);
+    await plugin.init();
+
+    plugin.initViewer(canvas, parent);
+
+    return plugin;
+}
+
+export async function loadStructure(
+    plugin: PluginContext,
+    url: string,
+    options?: { format?: string, isBinary?: boolean }
+) {
+    const data = await plugin.builders.data.download(
+        { url, isBinary: options?.isBinary }
+    );
+    const trajectory = await plugin.builders.structure.parseTrajectory(
+        data,
+        options?.format ?? 'mmcif' as any
+    );
+    const preset = await plugin.builders.structure.hierarchy.applyPreset(trajectory, 'default');
+    return preset;
+}
+```
+
+## Building the Library
+
+Add new commands to the `scripts` section of the `package.json` file
+
+```json
+"scripts": {
+  "build": "esbuild src/index.ts --bundle --outfile=./build/js/index.js --global-name=molstarLib",
+  "watch": "esbuild src/index.ts --bundle --outfile=./build/js/index.js --global-name=molstarLib --watch"
+}
+```
+
+and run the command `npm run build` (or `watch` for interactive development experience). This will create `build/js/index.js` file which can be imported with a `<script>` tag and the exported functions called view the `molstarLib` prefix (you can customize this parameter).
+
+## Using the Library
+
+Create file `build/index.html`:
+
+```html
+<!DOCTYPE html>
+<html lang="en">
+    <head>
+        <meta charset="utf-8" />

+            width: 800px;
+            height: 600px;
+        }
+    </style>
+    <script type="text/javascript" src="./js/index.js"></script>
+    <body>

+                const plugin = await molstarLib.initViewer("viewer");
+                await molstarLib.loadStructure(
+                    plugin,
+                    "https://models.rcsb.org/4hhb.bcif",
+                    { isBinary: true }
+                );
+            }
+            init();
+        </script>
+    </body>

+```
+
+After opening `index.html` in a browser, you should see

+## Using Mol* React UI
+
+The above example does not make use of the default Mol\* React UI and any UI components are therefore the author's responsibility. The below examples show how to (re)use the Mol\* React UI.
+
+- Create `src/ui.tsx`:
+```tsx
+import React from 'react';
+import { createRoot } from 'react-dom/client';
+
+import { DefaultPluginUISpec, PluginUISpec } from 'molstar/lib/mol-plugin-ui/spec';
+import { PluginUIContext } from 'molstar/lib/mol-plugin-ui/context';
+import { Plugin } from 'molstar/lib/mol-plugin-ui/plugin';
+
+export async function initViewerUI(element: string | HTMLDivElement, options?: { spec?: PluginUISpec }) {
+    const parent = typeof element === 'string' ? document.getElementById(element)! as HTMLDivElement : element;
+    const spec = { ...DefaultPluginUISpec(), ...options?.spec };
+    const plugin = new PluginUIContext(spec);
+    await plugin.init();
+
+    createRoot(parent).render(<Plugin plugin={plugin} />)
+
+    return plugin;
+}
+
+export async function loadStructure(plugin: PluginUIContext, url: string, options?: { format?: string, isBinary?: boolean }) {
+    const data = await plugin.builders.data.download({ url, isBinary: options?.isBinary });
+    const trajectory = await plugin.builders.structure.parseTrajectory(data, options?.format ?? 'mmcif' as any);
+    await plugin.builders.structure.hierarchy.applyPreset(trajectory, 'default');
+}
+```

+# Creating Plugin Instance
+
+
+## Intro
+
+What is a plugin? A plugin is a collection of modules that provide functionality to the `Mol*` UI. The plugin is responsible for managing the state of the viewer, internal and user interactions. It has been a previous point of confusion for new users of `Mol*` to associate the __viewer__ part of the library with what is further referred to as the __plugin__. These two are closely connected in the `molstar-plugin-ui` module, which is the user-facing part of the library and ultimately provides the viewer, but they are ultimately distinct. 
+
+
+It is recommended that you inspect the general class structure of [`PluginInitWrapper`](https://github.com/molstar/molstar/blob/6edbae80db340134341631f669eec86543a0f1a8/src/mol-plugin-ui/plugin.tsx#L41), [`PluginUIContext`](https://github.com/molstar/molstar/blob/6edbae80db340134341631f669eec86543a0f1a8/src/mol-plugin-ui/context.ts#L12) and [`PluginUIComponent`](https://github.com/molstar/molstar/blob/6edbae80db340134341631f669eec86543a0f1a8/src/mol-plugin-ui/base.tsx#L16) to better understand the flow of data and events in the plugin. 
+A passing analogy is that a [ `PluginContext` ](https://github.com/molstar/molstar/blob/6edbae80db340134341631f669eec86543a0f1a8/src/mol-plugin/context.ts#L71) is the engine that powers computation, rendering, events and subscriptions inside the molstar UI. All UI components depend on `PluginContext`. 
+
+
+
+There are 4 basic ways of instantiating the Mol* plugin.
+
+## ``Viewer`` wrapper
+
+- The most basic usage is to use the ``Viewer`` wrapper. This is best suited for use cases that do not require custom behavior and are mostly about just displaying a structure.
+- See ``Viewer`` class is defined in [src/apps/viewer/app.ts](https://github.com/molstar/molstar/blob/master/src/apps/viewer/app.ts) for available methods
+- See [options.ts](https://github.com/molstar/molstar/blob/master/src/apps/viewer/options.ts) for available plugin options
+- See [embedded.html](https://github.com/molstar/molstar/blob/master/src/apps/viewer/embedded.html) and [mvs.html](https://github.com/molstar/molstar/blob/master/src/apps/viewer/mvs.html) for example usage
+- Importing `molstar.js` will expose `molstar.lib` namespace that allow accessing various functionality without a bundler such as WebPack or esbuild. See the `mvs` example above for basic usage.
+- Alternative color themes can be used by importing `theme/dark.css` (or `light/blue`) instead of `molstar.css`
+
+### molstar.js and molstar.css sources
+
+- Download `molstar` NPM package and use the files from `build/viewer` diractory
+- Use `jsdelivr` CDN
+  - `<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/molstar@latest/build/viewer/molstar.js" />`
+  - `<link rel="stylesheet" type="text/css" href="https://cdn.jsdelivr.net/npm/molstar@latest/build/viewer/molstar.css" />`
+  - `@latest` can be replaced by a specific Mol* version, e.g., `@5.4.2`
+- Clone & build the GitHub repository
+  - This option allows for quite straightforward extension customization, e.g., not including movie export, which reduces the bundle size by ~0.5MB
+
+### Bundle size
+
+By default, the `Viewer` includes all the available extensions. This increases the bundle size significantly, especially by including the `mp4-export`, which is responsible for almost `0.5MB` of compressed bundle size. 
+It is quite easy to reduce this bundle size by cloning the Mol\* repository, editing [extensions.ts](https://github.com/molstar/molstar/blob/master/src/apps/viewer/options.ts) and rebuilding it with `npm run build:apps`. The new build will be available 
+in the `build/viewer` directory (the JS file you will find there is uncompressed, but your hosting setup should include automatic gzip compression, significantly reducing the size).
+
+Alternatively, you can explore building your own "viewer" using the base Mol\* library. For this, see the options below.
+
+
+### Example
+
+```HTML
+<style>
+    #app {
+        position: absolute;
+        left: 100px;
+        top: 100px;
+        width: 800px;
+        height: 600px;
+    }
+</style>
+<!-- 
+    molstar.js and .css are obtained from
+    - the folder build/viewer after cloning and building the molstar package 
+    - from the build/viewer folder in the Mol* NPM package
+-->
+<link rel="stylesheet" type="text/css" href="./molstar.css" />
+<script type="text/javascript" src="./molstar.js"></script>
+
+<div id="app"></div>
+
+<script type="text/javascript">
+    molstar.Viewer.create('app', {
+        layoutIsExpanded: false,
+        layoutShowControls: false,
+        layoutShowRemoteState: false,
+        layoutShowSequence: true,
+        layoutShowLog: false,
+        layoutShowLeftPanel: true,
+
+        viewportShowExpand: true,
+        viewportShowSelectionMode: false,
+        viewportShowAnimation: false,
+
+        pdbProvider: 'rcsb',
+        emdbProvider: 'rcsb',
+    }).then(viewer => {
+        viewer.loadPdb('7bv2');
+        viewer.loadEmdb('EMD-30210', { detail: 6 });
+    });
+</script>
+```
+
+### Using WebPack/esbuild/...
+
+When using WebPack (or other bundler) with the Mol* NPM package installed, the viewer class can be imported using 
+
+```ts
+import { Viewer } from 'molstar/lib/apps/viewer/app'
+
+function initViewer(target: string | HTMLElement) {
+    return Viewer.create(target, { /* options */}) // returns a Promise
+}
+```
+
+## ``PluginContext`` with built-in React UI
+
+- For more customization options it is possible to use the [``PluginContext``](https://github.com/molstar/molstar/blob/master/src/mol-plugin/context.ts) directly.
+- When creating the plugin instance it is possible to customize the [``PluginSpec``](https://github.com/molstar/molstar/blob/master/src/mol-plugin/spec.ts).
+- The default [``PluginSpec``](https://github.com/molstar/molstar/blob/master/src/mol-plugin/spec.ts) is available [here](https://github.com/molstar/molstar/blob/master/src/mol-plugin/spec.ts).
+- [``PluginConfig``](https://github.com/molstar/molstar/blob/master/src/mol-plugin/config.ts) object provides additional customization options.
+- See the [Viewer State Management](viewer-state.md) section for more information on customizing things like background.
+- See the [Data State Management](data-state.md) section for more information on build the state.
+
+```ts
+import { DefaultPluginUISpec, PluginUISpec } from 'molstar/lib/mol-plugin-ui/spec';
+import { createPluginUI } from 'molstar/lib/mol-plugin-ui';
+import { renderReact18 } from 'molstar/lib/mol-plugin-ui/react18';
+import { PluginConfig } from 'molstar/lib/mol-plugin/config';
+
+const MySpec: PluginUISpec = {
+    ...DefaultPluginUISpec(),
+    config: [
+        [PluginConfig.VolumeStreaming.Enabled, false]
+    ]
+}
+
+async function createPlugin(parent: HTMLElement) {
+    const plugin = await createPluginUI({
+      target: parent,
+      spec: MySpec,
+      render: renderReact18
+    });
+
+    const data = await plugin.builders.data.download({ url: '...' }, { state: { isGhost: true } });
+    const trajectory = await plugin.builders.structure.parseTrajectory(data, format);
+    await this.plugin.builders.structure.hierarchy.applyPreset(trajectory, 'default');
+
+    return plugin;
+}
+
+createPlugin(document.getElementById('app')!); // app is a <div> element with position: relative
+```
+
+To use the plugin (with the React UI) inside another React app:
+
+A single-plugin setup is shown the example below. In order to initialize multiple
+plugins, each with its own context and viewport, some extra steps are required (docs section to be added).
+
+```ts
+import { useEffect, createRef } from "react";
+import { createPluginUI } from "molstar/lib/mol-plugin-ui";
+import { renderReact18 } from "molstar/lib/mol-plugin-ui/react18";
+import { PluginUIContext } from "molstar/lib/mol-plugin-ui/context";
+/*  Might require extra configuration,
+see https://webpack.js.org/loaders/sass-loader/ for example.
+create-react-app should support this natively. */
+import "molstar/lib/mol-plugin-ui/skin/light.scss";
+
+declare global {
+  interface Window {
+    molstar?: PluginUIContext;
+  }
+}
+
+
+export function MolStarWrapper() {
+  const parent = createRef<HTMLDivElement>();
+
+  // In debug mode of react's strict mode, this code will
+  // be called twice in a row, which might result in unexpected behavior.
+  useEffect(() => {
+    // By default, react will call each useEffect twice if using Strict mode in
+    // debug build, it is recommended to disable strict mode for this reason if possible
+    async function init() {
+        window.molstar = await createPluginUI({
+          target: parent.current as HTMLDivElement,
+          render: renderReact18
+        });
+
+        const data = await window.molstar.builders.data.download(
+          { url: "https://files.rcsb.org/download/3PTB.pdb" }, /* replace with your URL */
+          { state: { isGhost: true } }
+        );
+        const trajectory =
+          await window.molstar.builders.structure.parseTrajectory(data, "pdb");
+        await window.molstar.builders.structure.hierarchy.applyPreset(
+          trajectory,
+          "default"
+        );
+    }
+    init();
+    return () => {
+      window.molstar?.dispose();
+      window.molstar = undefined;
+    };
+  }, []);
+
+  return <div ref={parent} style={{ width: 640, height: 480 }}/>;
+}
+
+```
+
+
+Furthermore, if it is desirable in your project to use the `molstar`'s React UI components, but you wish to alter or rearrange the layout, you should take a look at the signatures of [ `PluginUIComponent` ](https://github.com/molstar/molstar/blob/6edbae80db340134341631f669eec86543a0f1a8/src/mol-plugin-ui/base.tsx#L16) which every "control" subclasses. 
+
+
+[ `SequenceView` ](https://github.com/molstar/molstar/blob/6edbae80db340134341631f669eec86543a0f1a8/src/mol-plugin-ui/sequence.tsx#L221C4-L221C4), for example, can be used separately from the `PluginUI`. Yet you would need to pass the `PluginUIContext` to it in order for it to observe the changes in the state of the plugin. This can be done via a `PluginContextContainer`:
+```typescript
+// your_app.plugin: PluginUIContext
+...
+<div className="your_custom_ui">
+  <PluginContextContainer plugin={your_app.plugin}>
+    <SequenceView />
+  </PluginContextContainer>
+</div>
+```
+
+## Directly using Mol* React UI
+
+```ts
+class MolStarWrapper {
+  private resolveInit: () => void;
+  initialized = new Promise<boolean>(res => { this.resolveInit = () => res(true); });
+
+  private initCalled = false;
+  plugin: PluginUIContext;
+  async init() {
+    if (this.initCalled) return;
+    this.initCalled = true;
+    this.plugin = ...;
+    await this.plugin.init();
+    this.resolveInit();
+  }
+}
+
+function MolStar({ model }: { model: MolStarWrapper }) {
+  const [initialized, setInitialized] = useState(false);
+  useEffect(() => {
+     async function init() {
+       await model.init();
+       setInitialized(true);
+     }
+     init();
+  }, [model]);
+
+  if (!initialized) return <>Loading</>;
+  return <div style={{ ..., position: 'relative' }}>
+    <Plugin plugin={model.plugin} />
+  </div>;
+}
+```
+
+## ``PluginContext`` without built-in React UI
+
+- The [``PluginContext``](https://github.com/molstar/molstar/blob/master/src/mol-plugin/context.ts) can be instantiated without using the default React UI.
+
+```HTML
+<div id='molstar-parent' style='position: absolute; top: 0; left: 0; right: 0; bottom: 0'>
+    <canvas id='molstar-canvas' style='position: absolute; top: 0; left: 0; right: 0; bottom: 0'></canvas>
+</div>
+```
+
+```ts
+import { DefaultPluginSpec, PluginSpec } from 'molstar/lib/mol-plugin/spec';
+import { PluginContext  } from 'molstar/lib/mol-plugin/context';
+import { PluginConfig } from 'molstar/lib/mol-plugin/config';
+
+const MySpec: PluginSpec = {
+    ...DefaultPluginSpec(),
+    config: [
+        [PluginConfig.VolumeStreaming.Enabled, false]
+    ]
+}
+
+async function init() {
+    const plugin = new PluginContext(MySpec);
+    await plugin.init();
+
+    const canvas = <HTMLCanvasElement> document.getElementById('molstar-canvas');
+    const parent = <HTMLDivElement> document.getElementById('molstar-parent');
+
+    if (!(await plugin.initViewerAsync(canvas, parent))) {
+        console.error('Failed to init Mol*');
+        return;
+    }
+
+    // Example url:"https://files.rcsb.org/download/3j7z.pdb" 
+    // Example url:"https://files.rcsb.org/download/5AFI.cif" 
+    const data = await plugin.builders.data.download({ url: '...' }, { state: { isGhost: true } });
+    const trajectory = await plugin.builders.structure.parseTrajectory(data, format); //format is 'mmcif' or 'pdb' etc.
+    await plugin.builders.structure.hierarchy.applyPreset(trajectory, 'default');
+}
+
+```
+
+## ``Canvas3D`` without built-in state management
+
+- The ``PluginContext`` object from the above examples can be completely omitted.
+- See [Browser Tests](https://github.com/molstar/molstar/tree/master/src/tests/browser) for example usage.
+
+```ts
+const canvas = document.getElementById('canvas'); // parent <canvas> element
+const canvas3d = Canvas3D.create(Canvas3DContext.fromCanvas(canvas));
+canvas3d.animate();
+// use the canvas3d object here

+# Markdown Extension Manager
+
+The `markdownExtensions` manager in `PluginContext.manager` allows customizing
+the `Markdown` React component to enable executing commands and rendering custom content.
+
+The main use case of this is enriching [MolViewSpec](`https://molstar.org/mol-view-spec`) support.
+
+## API
+
+- `PluginContext.manager.markdownExtensions.register*` functions can be used to register extensions and state/data resolvers to make the the manager work with plugin extension
+- `PluginContext.manager.markdownExtensions.remove*` can be used to dynamically remove the above
+
+## Commands
+
+Extends Markdown Hyperlink syntax to support expressions of the form `[title](!c1=v1&c2=v2&...)` into an executable command. The command can be executed either on click, mouse enter, or mouse leave.
+
+Generally, the command should be URL encoded, e.g., `a b` => `a%20b` (in JS, `encodeURIComponent`, in Python `urllib.parse.quote_plus/urlencode`).
+
+### Built-in Commands
+
+- `center-camera` - Centers the camera
+- `apply-snapshot=key` - Loads snapshots with the provided key
+- `next-snapshot[=-1|1]` - Loads next/previous snapshot, the direction is optional and default to `1`
+- `play-snapshots` - Starts playback of state snapshots
+- `play-transition` - Plays an animation associated with the given snapshot
+- `stop-animation` - Stops currently playing animation
+- `focus-refs=ref1,ref2,...` - On click, focuses nodes with the provided refs
+- `highlight-refs=ref1,ref2,...` - On mouse over, highlights the provided refs
+- `query=...&lang=...&action=highlight,focus&focus-radius=...`
+    - `query` is an expression (e.g., `resn HEM` when using PyMol syntax)
+    - (optional) `lang` is one of `mol-script` (default), `pymol`, `vmd`, `jmol`
+    - (optional) `action` is an array of `highlight` (default), `focus` (multiple actions can be specified)
+    - (optional) `focus-radius` is extra distance applied when focusing the selection (default is `3`)
+    - Example: `[HEM](!query=resn%20HEM%26lang=pymol&action=highlight,focus)` highlights or focuses the HEM residue (the query must be URL encoded because it contains spaces and possibly other special characters)
+- `play-audio=src`, `toggle-audio[=src]`, `stop-audio`, `pause-audio`, `dispose-audio` - Audio playback support
+
+## Custom Content
+
+Extends Markdown Image syntax to support expressions of the form `![alt](!c1=v1&c2=v2&...)` to render custom elements instead.
+
+### Built-in Custom Content
+- `color-swatch=color` - Renders a box with the provided color
+-  Color palettes:
+    - `color-palette-name=name` - Renders a gradient with the provided named color palette (see `mol-util/color/lists.ts` for supported color schemes)
+    - `color-palette-colors=color1,color2` - Renders a gradient with the provided colors
+    - `color-palette-width=CCS-value` - Specifies the width of the element, defaults to `150px`
+    - `color-palette-height=CCS-value` - Specified the height of the element, defaults to `0.5em`
+    - `color-palette-discrete` - Renders discrete color list instead of interpolating
+
+
+## Example
+
+```markdown
+### Highlight/Focus:
+- ![blue](!color-swatch=blue) [polymer](!highlight-refs=polymer&focus-refs=polymer)
+- ![blue](!color-swatch=red) [ligand](!highlight-refs=ligand&focus-refs=ligand)
+- [both](!highlight-refs=polymer,ligand&focus-refs=polymer,ligand)
+
+### Color Palettes
+|name|visual|
+|---:|---|
+|viridis|![viridis](!color-palette-name=viridis)|
+|rainbow (discrete)|![simple-rainbow](!color-palette-name=simple-rainbow&color-palette-discrete)|
+|custom|![custom](!color-palette-colors=red,#00ff00,rgb(0,0,255))|
+
+### Camera controls
+- [center](!center-camera)
+
+### Image embedded in MVSX file
+![mvsx image](logo.png)
+```
+
+This works with the MolViewSpec state built by:
+
+```py
+import molviewspec as mvs
+
+builder = mvs.create_builder()
+
+assets = {
+    "1cbs.cif": "https://files.wwpdb.org/download/1cbs.cif",
+    "logo.png": "https://molstar.org/img/molstar-logo.png",
+}
+
+model = (
+    builder.download(url="1cbs.cif")
+        .parse(format="mmcif")
+        .model_structure()
+)
+(
+    model.component(selector="polymer")
+    .representation(ref="polymer")
+    .color(color="blue")
+)
+(
+    model.component(selector="ligand")
+    .representation(ref="ligand")
+    .color(color="red")
+)
+
+mvsx = mvs.MVSX(
+    data=builder.get_state(
+        description="""..."""  # inline the code above

+# Selections
+
+
+## Basic Concepts
+
+### Location
+
+The selection model in Mol\* is based on a generic concept called *location*. A location is a pointer to a selectable element within a scene. For example:
+
+- A structure element location (an atom or a coarse element) is an object composed of `{ structure: Structure, unit: Unit, element: UnitIndex }` (you can think of a `Unit` as a generalized chain)
+- A bond location is very similar to structure element, requiring pointers to two units and elements
+- A "shape" (generally a mesh) location consists of pointer to the parent shape and a group of triangles
+
+### Loci
+
+Structures and other renderable elements generally consist of many locations and simply using a list of locations would be 
+prohibitively expensive (e.g., large selections in structures with hundreds of thousands of atoms).
+
+This is why Mol\* introduces
+the concept of `Loci` &mdash; a compressed representation of multiple locations. Instead of having a list of structure element locations (`{ structure: Structure, unit: Unit, element: UnitIndex }[]`), the representation becomes (simplified) `{ structure: Structure, unit: Unit, elements: OrderedSet<UnitIndex> }`. The ordered set can be further compressed for continuous ranges, keeping only the index of the 1st and last element.
+
+### Bundle
+
+Locations and loci point to the raw JavaScript data structures representing the underlying molecules, making them not serializable in JSON. A *bundle* is a serializable version of the loci.
+
+### Structure Queries
+
+Defining selections directly using the loci would be very cumbersome. For this reason, Mol\* includes the [MolQl query language](https://molql.org) to help define selections.
+
+
+## Selection Methods
+
+Assuming you have a model already loaded into the plugin (see [Creating Plugin Instance](./instance.md)), these are some of the methods you can use to create selections.
+
+### MolQL (`mol-script`) language
+
+[MolQL](https://molql.org) (`mol-script`) is a language for addressing crystallographic structures and is a part of the Mol* library found at `https://github.com/molstar/molstar/tree/master/src/mol-script`. It can be used against the Molstar plugin as a query language and transpiled against multiple external molecular visualization libraries(see [here](https://github.com/molstar/molstar/tree/master/src/mol-script/transpilers)).
+
+**Example:** Querying a structure for a specific chain and residue range
+
+Select residues with `12<res_id<200 of chain with auth_asym_id=A`
+
+```typescript
+import { compileIdListSelection } from 'molstar/lib/mol-script/util/id-list'
+
+const query = compileIdListSelection('A 12-200', 'auth');
+window.molstar?.managers.structure.selection.fromCompiledQuery('add',query);
+```
+
+### Selection Queries
+
+Another way to create a selection is via a `SelectionQuery` object. This is a more programmatic way to create a selection. The following example shows how to select a chain and a residue range using a `SelectionQuery` object.
+This relies on the concept of `Expression` which is basically a intermediate representation between a Molscript statement and a selection query. 
+ 
+**Example:** Select residues 10-15 of chains A and F in a structure using a `SelectionQuery` object
+
+```typescript
+import { MolScriptBuilder as MS, MolScriptBuilder } from 'molstar/lib/mol-script/language/builder';
+import { Expression } from 'molstar/lib/mol-script/language/expression';
+import {  StructureSelectionQuery } from 'molstar/lib/mol-plugin-state/helpers/structure-selection-query'
+
+
+export function select_multiple() {
+
+ const args = [['A', 10, 15], ['F', 10, 15]]
+ const groups: Expression[] = [];
+ for (var chain of args) {
+   groups.push(MS.struct.generator.atomGroups({
+     'chain-test': MS.core.rel.eq([MolScriptBuilder.struct.atomProperty.macromolecular.auth_asym_id(), chain[0]]),
+     'residue-test': MS.core.rel.inRange([MolScriptBuilder.struct.atomProperty.macromolecular.label_seq_id(), chain[1], chain[2]])
+   }));
+ }
+ var sq = StructureSelectionQuery('residue_range_10_15_in_A_and_F', MS.struct.combinator.merge(groups))
+ mstar.managers.structure.selection.fromSelectionQuery('set', sq)
+}
+```
+
+Complex queries can be constructed by combining primitive queries at the level of [`chain-test`, `residue-test`, `entity-test`, etc] (https://github.com/molstar/molstar/blob/6edbae80db340134341631f669eec86543a0f1a8/src/mol-script/language/symbol-table/structure-query.ts#L88C4-L94C112) by combining them via logical connectives provided in the `MolscriptBuilder.core.rel` as above.
+
+Inspect these examples to get a better feeling for this syntax: `https://github.com/molstar/molstar/blob/6edbae80db340134341631f669eec86543a0f1a8/src/mol-plugin-state/helpers/structure-selection-query.ts#L88-L580`
+
+
+Furthermore, a query made this way can be converted to a `Loci` object which is important in many parts of the libary:
+```typescript
+// Select residue 124 of chain A and convert to Loci
+const Q = MolScriptBuilder;
+var sel = Script.getStructureSelection(Q => Q.struct.generator.atomGroups({
+  'chain-test': Q.core.rel.eq([Q.struct.atomProperty.macromolecular.auth_asym_id(), A]),
+  'residue-test': Q.core.rel.eq([Q.struct.atomProperty.macromolecular.label_seq_id(), 124]),
+}), objdata)
+
+let loci = StructureSelection.toLociWithSourceUnits(sel);
+```
+
+### Query Functions
+
+Instead of building expressions, query functions can be created directly, e.g.:
+
+```ts
+import { atoms } from 'mol-model/structure/query/queries/generators';
+
+const query = atoms({
+  residueTest: ctx => {
+    const seqId = StructureProperties.residue.label_seq_id(ctx.element);
+    return seqId > 10 && seqId < 25;
+  },
+});
+
+const selection = query(new QueryContext(structure));
+// ...
+```
+
+### Selection Schema
+
+For simple selections, the `StructureElement.Schema` can be used to reference elements within a protein structure using mmCIF `atom_site` field names, e.g.:
+
+```ts
+const ala121: StructureElement.Schema = { label_asym_id: 'A', label_seq_id: 121 };
+const residues: StructureElement.Schema = { 
+  items: {
+    auth_asym_id: ['A', 'B'],
+    auth_seq_id: [10, 11],
+  }
+};
+
+const loci = StructureElement.Loci.fromSchema(structure, residues);
+```
+
+Usually, a code editor such as VS Code will auto-suggest all the available field names.
+
+### Using the `hierarchy` manager
+
+It is possible to select a subcomponent's data directly from the plugin manager.
+
+```typescript 
+import { Structure } from '../mol-model/structure';
+
+const ligandData = plugin.managers.structure.hierarchy.selection.structures[0]?.components[0]?.cell.obj?.data;
+const ligandLoci = Structure.toStructureElementLoci(ligandData as any);
+
+plugin.managers.camera.focusLoci(ligandLoci);
+plugin.managers.interactivity.lociSelects.select({ loci: ligandLoci });
+```
+
+## Selection Events
+If you want to subscribe to selection events (e.g. to change external state in your application based on a user selection), you can use: `plugin.behaviors.interaction.click.subscribe`
+
+Here's an example of passing in a React "set" function to update selected residue positions.
+```typescript
+import {
+  Structure,
+  StructureProperties,
+} from "molstar/lib/mol-model/structure"
+// setSelected is assumed to be a "set" function returned by useState
+// (selected: any[]) => void
+plugin.behaviors.interaction.click.subscribe(
+  (event: InteractivityManager.ClickEvent) => {
+    const selections = Array.from(
+      plugin.managers.structure.selection.entries.values()
+    );
+    // This bit can be customized to record any piece information you want
+    const localSelected: any[] = [];
+    for (const { structure } of selections) {
+      if (!structure) continue;
+      Structure.eachAtomicHierarchyElement(structure, {
+        residue: (loc) => {
+          const position = StructureProperties.residue.label_seq_id(loc);
+          localSelected.push({ position });
+        },
+      });
+    }
+    setSelected(localSelected);
+  }
+)
+```
+
+## Helper Functions
+
+Given an `Expression`, `QueryFn`, or `StructureElement.Schema` it is possible to use `fromExpression/Query/Schema` functions on `StructureElement.Loci` and `StructureElement.Bundle`.
+
+### `Viewer` app
+
+The `Viewer` app provides the `structureInteractivity` function which allows easy selection/highlighting of the loaded structure. For example:
+
+```ts
+viewer.structureInteractivity({
+    elements: { beg_auth_seq_id: 10, end_auth_seq_id: 50 },
+    action: 'select',
+});
+```

+# Structure Superposition
+
+Mol* provides utilities for superposing protein structures, including both sequence-independent (RMSD-based) and structure-based (TM-align) methods.
+
+## RMSD-based Superposition
+
+The basic superposition method uses the Kabsch algorithm to minimize RMSD between corresponding atoms:
+
+```typescript
+import { superpose } from 'molstar/lib/mol-model/structure/structure/util/superposition';
+import { StructureSelection, QueryContext } from 'molstar/lib/mol-model/structure';
+import { compile } from 'molstar/lib/mol-script/runtime/query/compiler';
+import { MolScriptBuilder as MS } from 'molstar/lib/mol-script/language/builder';
+
+// Create a query for C-alpha atoms
+const caQuery = compile<StructureSelection>(MS.struct.generator.atomGroups({
+    'atom-test': MS.core.rel.eq([MS.struct.atomProperty.macromolecular.label_atom_id(), 'CA'])
+}));
+
+// Get selections from two structures
+const sel1 = StructureSelection.toLociWithCurrentUnits(caQuery(new QueryContext(structure1)));
+const sel2 = StructureSelection.toLociWithCurrentUnits(caQuery(new QueryContext(structure2)));
+
+// Compute superposition (returns transformation matrices)
+const transforms = superpose([sel1, sel2]);
+
+// transforms[0].bTransform contains the Mat4 to superpose structure2 onto structure1
+```
+
+## TM-align Superposition
+
+TM-align is a structure-based alignment algorithm that produces the TM-score, a length-independent metric for comparing protein structures. Unlike RMSD, TM-score is normalized to [0, 1] and is more robust for comparing proteins of different sizes.
+
+### Basic Usage
+
+```typescript
+import { tmAlign } from 'molstar/lib/mol-model/structure/structure/util/tm-align';
+import { StructureElement } from 'molstar/lib/mol-model/structure';
+
+// Get C-alpha Loci from two structures (see selection examples above)
+const loci1: StructureElement.Loci = /* ... */;
+const loci2: StructureElement.Loci = /* ... */;
+
+// Run TM-align
+const result = tmAlign(loci1, loci2);
+
+console.log('TM-score (normalized by structure 1):', result.tmScoreA);
+console.log('TM-score (normalized by structure 2):', result.tmScoreB);
+console.log('RMSD:', result.rmsd);
+console.log('Aligned residues:', result.alignedLength);
+
+// result.bTransform is a Mat4 to transform structure2 onto structure1
+```
+
+### TM-align Result
+
+The `tmAlign` function returns a `TMAlignResult` object with the following properties:
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `bTransform` | `Mat4` | Transformation matrix to superpose structure B onto A |
+| `tmScoreA` | `number` | TM-score normalized by length of structure A |
+| `tmScoreB` | `number` | TM-score normalized by length of structure B |
+| `rmsd` | `number` | RMSD of aligned residue pairs (in Angstroms) |
+| `alignedLength` | `number` | Number of aligned residue pairs |
+| `sequenceIdentity` | `number` | Sequence identity of aligned residues (0-1) |
+| `alignmentA` | `number[]` | Indices of aligned residues in structure A |
+| `alignmentB` | `number[]` | Indices of aligned residues in structure B |
+
+### Understanding TM-score
+
+The TM-score is calculated as:
+
+$$\text{TM-score} = \frac{1}{L} \sum_{i=1}^{L_{ali}} \frac{1}{1 + (d_i/d_0)^2}$$
+
+Where:
+- $L$ is the length of the reference protein
+- $L_{ali}$ is the number of aligned residues
+- $d_i$ is the distance between the $i$-th pair of aligned residues after superposition
+- $d_0 = 1.24 \sqrt[3]{L - 15} - 1.8$ is a length-dependent normalization factor
+
+**TM-score interpretation:**
+- TM-score > 0.5: Generally indicates proteins with the same fold
+- TM-score > 0.17: Generally indicates proteins with random structural similarity
+
+### Low-level API
+
+For direct coordinate-based alignment without structures, use the `TMAlign` namespace:
+
+```typescript
+import { TMAlign } from 'molstar/lib/mol-math/linear-algebra/3d/tm-align';
+
+// Create position arrays
+const posA = TMAlign.Positions.empty(lengthA);
+const posB = TMAlign.Positions.empty(lengthB);
+
+// Fill in coordinates
+for (let i = 0; i < lengthA; i++) {
+    posA.x[i] = /* x coordinate */;
+    posA.y[i] = /* y coordinate */;
+    posA.z[i] = /* z coordinate */;
+}
+// ... similarly for posB
+
+// Compute alignment
+const result = TMAlign.compute({ a: posA, b: posB });
+```
+
+### Complete Example: Aligning Two PDB Structures
+
+```typescript
+import { PluginContext } from 'molstar/lib/mol-plugin/context';
+import { MolScriptBuilder as MS } from 'molstar/lib/mol-script/language/builder';

+# Load Trajectory from a Custom Format
+
+This section shows a high level example for loading trajectory from custom data in specialized plugin instances. A more complete solution is available for example in form of the [G3D format extension](https://github.com/molstar/molstar/tree/master/src/extensions/g3d).
+
+## Defining and Using a Custom Transformer
+
+```ts
+import { StateTransformer } from 'molstar/lib/mol-state';
+
+const CreateTransformer = StateTransformer.builderFactory('custom-namespace');
+
+export interface CustomTrajectoryData {
+    // ...
+}
+
+export const TrajectoryFromCustomData = CreateTransformer({
+    name: 'trajectory-from-custom-data',
+    display: 'Trajectory',
+    from: PluginStateObject.Root,
+    to: PluginStateObject.Molecule.Trajectory,
+    params: {
+        data: PD.Value<CustomTrajectoryData>(void 0 as any, { isHidden: true }),
+    },
+})({
+    apply({ params }) {
+        return Task.create('Trajectory', async (ctx) => {
+            const models = await customParse(params.data, ctx);
+            return new PluginStateObject.Molecule.Trajectory(models, {
+                label: 'Trajectory',
+            });
+        });
+    },
+});
+```
+
+The ``customParse`` function can usually be implemented 
+by modifying/extending an [existing parser already available in Mol*](https://github.com/molstar/molstar/tree/master/src/mol-model-formats/structure).
+
+To use the transformer:
+
+```ts
+const data: CustomTrajectoryData = await (await fetch(url)).json();
+const trajectory = await plugin.build().toRoot().apply(TrajectoryFromCustomData, { data }).commit();
+// Create the representation
+await plugin.builders.structure.hierarchy.applyPreset(trajectory, 'default');
+```
+
+## Using Mol* to Download the Data
+
+```ts
+export const TrajectoryFromCustomData = CreateTransformer({
+    name: 'trajectory-from-custom-data',
+    display: 'Trajectory',
+    from: PluginStateObject.Data.String, // or PluginStateObject.Data.Binary
+    to: PluginStateObject.Molecule.Trajectory,
+})({
+    apply({ a }) {
+        return Task.create('Trajectory', async (ctx) => {
+            const models = await customParse(a.data, ctx);
+            return new PluginStateObject.Molecule.Trajectory(models, {
+                label: 'Trajectory',
+            });
+        });
+    },
+});
+
+//////////////
+
+const data = await plugin.builders.data.download({ url, isBinary });
+const trajectory = await plugin.build().to(data).apply(TrajectoryFromCustomData, { data }).commit();
+await plugin.builders.structure.hierarchy.applyPreset(trajectory, 'default');

+# Viewer State Management
+
+## ``Canvas3D`` Properties
+Properties of the [``Canvas3D``](https://github.com/molstar/molstar/blob/master/src/mol-canvas3d/canvas3d.ts) can be 
+changed using [``PluginCommands``](https://github.com/molstar/molstar/blob/master/src/mol-plugin/commands.ts).  
+
+
+### Change background, highlight, or select color
+```ts
+import { ColorNames } from 'molstar/lib/mol-util/color/names';
+import { PluginCommands } from 'molstar/lib/mol-plugin/commands';
+
+const renderer = plugin.canvas3d!.props.renderer;
+PluginCommands.Canvas3D.SetSettings(plugin, { settings: { renderer: { ...renderer, backgroundColor: ColorNames.red /* or: 0xff0000 as Color */ } } });
+```
+Similarly, `highlightColor` and `selectColor` can be updated.
+
+
+## Interactivity
+
+Interactivity in Mol* is based on the concept of ``Loci``. A ``Loci`` usually references a collection of objects and can be created by a [``Selection``](selections.md). For example, the
+``Loci`` captures all atoms in the chain with label_asym_id B of a protein:
+```ts
+import { Script } from 'molstar/lib/mol-script/script';
+import { StructureSelection } from 'molstar/lib/mol-model/structure/query';
+
+const data = plugin.managers.structure.hierarchy.current.structures[0]?.cell.obj?.data;
+if (!data) return;
+
+const selection = Script.getStructureSelection(Q => Q.struct.generator.atomGroups({
+    'chain-test': Q.core.rel.eq(['B', Q.ammp('label_asym_id')])
+}), data);
+const loci = StructureSelection.toLociWithSourceUnits(selection);
+```
+A ``Loci`` can be used to trigger custom [``Behaviors``](#behaviors).
+
+
+### Log message to Mol* console
+The built-in console in the bottom center of the plugin shows log entries.
+```ts
+plugin.log.message('This message will appear in the Mol* console');
+```
+Other log levels are: `info`, `warn`, and `error`.
+
+
+### Show toast message
+Toast messages will appear in the bottom right of the plugin and will linger for a limited time before disappearing.
+```ts
+import { PluginCommands } from 'molstar/lib/mol-plugin/commands';
+
+PluginCommands.Toast.Show(plugin, {
+    title: 'Custom Message',
+    message: 'A custom toast message that will disappear after 2 seconds.',
+    key: 'toast-custom',
+    timeoutMs: 2000
+});
+```
+
+## Behaviors
+
+The state of the Mol* plugin is usually governed by dynamic behaviors which can be set up in initial plugin specification or updated during the plugin runtime. This allows for high modularity and customizability of individual plugin instances.
+
+
+### Highlight ``Loci``
+Highlighting adds a transient overpaint to a representation that will linger until the mouse enters hovers over another 
+object. Highlights can be applied to a previously defined ``Loci`` by:
+```ts
+plugin.managers.interactivity.lociHighlights.highlightOnly({ loci }); // loci: Loci
+```
+Reset all highlights by:
+```ts
+plugin.managers.interactivity.clearHighlights();
+```
+
+
+### Select ``Loci``
+
+Selected elements will appear with distinct visuals and, if applicable, the corresponding sequence positions will be 
+shown in the Sequence Viewer panel. Selections persist until removed, for example by clicking the background. A ``Loci``
+is selected by:
+```ts
+plugin.managers.interactivity.lociSelects.select({ loci }); // loci: Loci
+```
+
+Deselect a specific ``Loci`` by:
+```ts
+plugin.managers.interactivity.lociSelects.deselect({ loci }); // loci: Loci
+```
+To deselect everything:
+```ts
+plugin.managers.interactivity.lociSelects.deselectAll();
+```
+
+
+### Focus ``Loci``
+The focus representation shows a ``Loci`` in ball-and-stick representation and, additionally, visualizes non-covalent
+interactions between atoms of the ``Loci`` as well as interactions with surrounding residues (default: 5 Å).
+```ts
+plugin.managers.structure.focus.setFromLoci(loci);
+```
+Extend an existing focus representation by:
+```ts
+plugin.managers.structure.focus.addFromLoci(loci); // loci: Loci
+```
+Reset by:
+```ts
+plugin.managers.structure.focus.clear();
+```
+
+
+### Zoom ``Loci``
+A ``Loci`` can also be used to manipulate the camera. Zoom in by:
+```ts
+plugin.managers.camera.focusLoci(loci); // loci: Loci
+```
+
+Restore the default camera position by:
+```ts
+plugin.managers.camera.reset();
+```
+
+### Turn off view resetting on new representations
+A new representation via something like
+```ts
+.apply(StateTransforms.Representation.VolumeRepresentation3D, ...)
+```
+can reset the view to make the whole representation visible.
+When one wants to keep the view the same instead of having the rep reset the view,
+keep the view constant by:
+```ts
+plugin.canvas3d?.setProps({ camera: { manualReset: true } });
+```

-Model Server
-============
-
-Model Server is a tool for preprocessing and querying macromolecular structure data.
-
-Installing and Running
-=====================
-
-Requires nodejs 8+.
-
-## From GitHub
-
-```
-git clone https://github.com/molstar/molstar
-npm install
-```
-
-Afterwards, build the project source:
-
-```
-npm run build-tsc
-```
-
-and run the server by 
-
-```
-node lib/commonjs/servers/model/server/server
-```
-
-## From NPM
-
-```
-npm install --production molstar
-./model-server 
-```
-
-(or ``node node_modules\.bin\model-server`` in Windows).
-
-The NPM package contains all the tools mentioned here as "binaries":
-
-- ``model-server``
-- ``model-server-query``
-- ``model-server-preprocess``
-
-
-### Production use
-
-In production it is required to use a service that will keep the server running, such as [forever.js](https://github.com/foreverjs/forever).
-
-
-### Memory issues
-
-Sometimes nodejs might run into problems with memory. This is usually resolved by adding the ``--max-old-space-size=8192`` parameter.
-
-## Preprocessor
-
-The preprocessor application allows to add custom data to CIF files and/or convert CIF to BinaryCIF. ``node lib/commonjs/servers/model/preprocess`` or ``model-server-preprocess`` binary from the NPM package.
-
-
-## Local Mode
-
-The server can be run in local/file based mode using ``node lib/commonjs/servers/model/query`` (``model-server-query`` binary from the NPM package).
-
-Custom Properties
-=================
-
-This feature is still in development.
-
-It is possible to provide property descriptors that transform data to internal representation and define how it should be exported into one or mode CIF categories. Examples of this are located in the ``mol-model-props`` module and are linked to the server in the config and ``servers/model/properties``.

-What is VolumeServer
-=====================
-
-VolumeServer is a service for accessing subsets of volumetric density data. It automatically downsamples the data depending on the volume of the requested region to reduce the bandwidth requirements and provide near-instant access to even the largest data sets.
-
-It uses the text based CIF and BinaryCIF formats to deliver the data to the client. 
-
-For quick info about the benefits of using the server, check out the [examples](examples.md).
-
-Installing and Running
-=====================
-
-Requires nodejs 8+.
-
-## From GitHub
-
-```
-git clone https://github.com/molstar/molstar
-npm install
-```
-
-Afterwards, build the project source:
-
-```
-npm run build-tsc
-```
-
-and run the server by 
-
-```
-node lib/commonjs/servers/volume/server
-```
-
-## From NPM
-
-```
-npm install --production molstar
-./volume-server 
-```
-
-(or ``node node_modules\.bin\volume-server`` in Windows).
-
-The NPM package contains all the tools mentioned here as "binaries":
-
-- ``volume-server``
-- ``volume-server-pack``
-- ``volume-server-query``
-
-
-### Production use
-
-In production it is required to use a service that will keep the server running, such as [forever.js](https://github.com/foreverjs/forever).
-
-
-### Memory issues
-
-Sometimes nodejs might run into problems with memory. This is usually resolved by adding the ``--max-old-space-size=8192`` parameter.
-
-
-## Preparing the Data
-
-For the server to work, CCP4/MAP (models 0, 1, 2 are supported) input data need to be converted into a custom block format. 
-To achieve this, use the ``pack`` application (``node lib/commonjs/servers/volume/pack`` or ``volume-server-pack`` binary from the NPM package).
-
-## Local Mode
-
-The program  ``lib/commonjs/servers/volume/pack`` (``volume-server-query`` in NPM package) can be used to query the data without running a http server.
-
-## Navigating the Source Code
-
-The source code is split into 2 mains parts: ``pack`` and ``server``:
-
-- The ``pack`` part provides the means of converting CCP4 files into the internal block format.
-- The ``server`` includes
-  - ``query``: the main part of the server that handles a query. ``execute.ts`` is the "entry point".
-  - ``algebra``: linear, "coordinate", and "box" algebra provides the means for calculations necessary to concent a user query into a menaningful response.
-  - API wrapper that handles the requests.
-
-Consuming the Data 
-==================
-
-The data can be consumed in any (modern) browser using the [ciftools library](https://github.com/molstar/ciftools) (or any other piece of code that can read text or binary CIF).
-
-The [Data Format](DataFormat.md) document gives a detailed description of the server response format.
-
-As a reference/example of the server usage is available in Mol* ``mol-plugin`` module.
