-# 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">
-            var molstarViewer;
-            molstar.Viewer.create('app', { layoutIsExpanded: false }).then(viewer => {
-                molstarViewer = viewer;
-                viewer.loadPdb('5elb');
-            });
-        </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`.

-     * NOTE 1) Each step is drawn with 4 mesh groups. We need to divide/multiply by 4 to convert between steps and mesh groups.
-     * NOTE 2) Molstar will create a mesh only for the asymmetric unit. When the entire biological assembly
-     *         is displayed, Molstar just copies and transforms the mesh. This means that even though the mesh
-     *         might be displayed multiple times, groupIds of the individual blocks in the mesh will be the same.
-     *         If there are multiple copies of a mesh, Molstar needs to be able to tell which block belongs to which copy of the mesh.
-     *         To do that, Molstar adds an offset to groupIds of the copied meshes. Offset is calculated as follows:
-     *
-     *         offset = NumberOfBlocks * UnitIndex
-     *
-     *         "NumberOfBlocks" is the number of valid Location objects got from LocationIterator *or* the greatest groupId set by
-     *         the mesh generator - whichever is smaller.
-     *
-     *         UnitIndex is the index of the Unit the mesh belongs to, starting from 0. (See "unitMap" in the Structure object).
-     *         We can also get this index from the value "instanceId" of the "pickingId" object.
-     *
-     *         If this offset is not applied, picking a piece of one of the copied meshes would actually pick that piece in the original mesh.
-     *         This is particularly apparent with highlighting - hovering over items in a copied mesh incorrectly highlights those items in the source mesh.
-     *
-     *         Molstar can take advantage of the fact that ElementLoci has a reference to the Unit object attached to it. Since we cannot attach ElementLoci
-     *         to a step, we need to calculate the offseted groupId here and pass it as part of the DataLoci.

-# SB NCBR extensions
-
-## Partial charges
-
-This extension visualizes partial atomic charges for atoms and residues. The extension reads charge data of a structure from a mmcif file and displays them as a color gradient on the atoms/residues. The coloring uses two gradients: one for positive charges (white-to-blue) and one for negative charges (red-to-white). The color is interpolated between the appropriate gradient based on the charge value. The extension also displays the charge values in the description label when an atom/residue is selected.
-
-### How to use
-
-To visualize partial charges, you need to provide a mmcif file with the structure and its charges. The charges are stored under the following categories:
-
-```
-_sb_ncbr_partial_atomic_charges_meta.id         # id of the charges (e.g. 1)
-_sb_ncbr_partial_atomic_charges_meta.type       # type of the charges (optional, e.g. 'empirical')
-_sb_ncbr_partial_atomic_charges_meta.method     # calculation method name (e.g. 'QEq', 'SQE+qp/Schindler 2021 (PUB_pept)')
-
-_sb_ncbr_partial_atomic_charges.type_id         # id of the charges (pointer to _sb_ncbr_partial_atomic_charges_meta.id)
-_sb_ncbr_partial_atomic_charges.atom_id         # atom id (pointer to _atom_site.id)
-_sb_ncbr_partial_atomic_charges.charge          # partial atomic charge 
-```
-> Note that the mmcif item `_partial_atomic_charges_meta.method` is used as a description of the charge set in the UI (described in *Controls*).
-
-The extension will automatically read the charges from the mmcif file and color the structure accordingly.
-
-### Controls
-
-The extension provides controls for setting the color gradient range and for selecting charge type (atom charges or residue charges).
-These controls are available in Color Theme settings for 3D Representation cells in the State Tree UI.
-
-There is also a dropdown menu for switching between charge sets.
-These controls are available in Custom Model Properties settings for Model cell in the State Tree UI.

-# Chemical Component Dictionary Extension
-
-The [Chemical Component Dictionary (CCD)](https://www.wwpdb.org/data/ccd) describes all small molecules and monomers found in PDB entries. The dictionary provides a plethora of additional information not present in wwPDB archive structures such as chemical descriptors (SMILES & InChI) and stereochemical assignments, information on bond order and more. Most notably, the CCD provides 2 sets of coordinates:
- `ideal`: idealized/minimized coordinates, obtained using Molecular Networks' Corina, and if there are issues, OpenEye's OMEGA
- `model`: coordinates extracted from an archive structure
-
-## How to Load a Component from URL
-1. "Download Structure" -- switch "Source" to "URL"
-2. Enter URL of component, e.g. https://files.rcsb.org/ligands/view/HEM.cif, leave "Format" as is
-3. Click "Apply"
-
-This parses the corresponding component into 2 models (1st: `ideal` coordinates, 2nd: `model` coordinates) and applies the default representaiton to the 1st model. `model` coordinates are available as 2nd model. Click the canvas to re-focus if you don't see anything after switching models due to the coordinates being far away.
-
-## How to Visualize Components
-There's a dedicated representation preset that faciliates the comparison of `ideal` and `model` coordinates.
-
-1. Load a component as described above
-2. Switch structure preset to "Chemical Component" (button in the top-right, in the "Structure" panel)
-
-This creates a dedicated component for `ideal` as well as `model` coordinates and represents them as ball-and-stick. Initially, only `ideal` coordinates are shown. After toggling the visibility of `model` coordinates, they appear superimposed with the `ideal` coordinates. 
-
