-# 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`.

-    }
-}
-```
-
-### 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``.

-# 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-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](./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. |
-| `--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>

-        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 following example is a minimal HTML using this functionality:
-

-        <script type="text/javascript" src="./molstar.js"></script>
-        <script type="text/javascript">
-            var molstarViewer;
-            molstar.Viewer.create('app', { layoutIsExpanded: false }).then(viewer => {

-            });
-        </script>
-    </body>
-</html>
-```
-
-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 ([runVisualizeTunnels](../../../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 ([runVisualizeTunnel](../../../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);

-# 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/context.ts#L71) 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 much 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 and options.
-
-Example usage without using WebPack:
-
-```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>
-```
-
-When using WebPack (or possibly other build tool) with the Mol* NPM package installed, the viewer class can be imported using 
-
-```ts
-import { Viewer } from 'molstar/build/viewer/molstar'
-
-function initViewer(target: string | HTMLElement) {
-    return new Viewer(target, { /* options */})
-}
-```
-
-## ``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.

-To use the plugin (with the React UI) inside another React app:

-plugins, each with its own context and viewport, some extra steps are required (docs section to be added).
-
-```ts

-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(() => {
-    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 } }
-        );

-        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>;
-}
-```

-# Selections
-
-
-Assuming you have a model already loaded into the plugin (see [Creating Plugin Instance](./instance.md)), these are some of the following method you can select structural data.
-
-### Selecting directly from the `hierarchy` manager
-
-One can 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 callbacks
-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);
-  }
-)
-```
-
-### `Molscript` language
-
-Molscript 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)).
-
-### 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. 
- 
-### 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);
-```

-# 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 } });
-```

+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.
