Tunnels extension

[vDusky]

Description

Created extension for visualization of tunnels.

Actions

• [x] Added transformers
• [x] Created algorithm for visualization
• [x] Added examples for visualization

[arose]

Is this ready for testing? Are there example files available? Could you add a Preset for files with an PDB ID?

@arose got any comments too?

I will have a closer look on the weekend. In general I like the pattern in the assembly-symmetry extension more where you have 1) the data in a structure property and 2) either get it from an url or a file (can be stored in the session), 3) have a transform from structure to representation.

And to reiterate, I really would like to see a Preset so it is readily usable for structure with a PDB ID.

@arose the main use case for this was to enable https://channelsdb2.biodata.ceitec.cz/ and @vDusky already added the DownloadTunnels action to be able to set up the scene.

Although, you are right the assembly-symmetry is a nice approach as well. @vDusky, in addition to the DownloadTunnels action, can you please add/register a preset similar to this? It should show up in the menu afterwards and allow loading channels even for existing entries:

EDIT: Never mind there was just no entry for 3pqr (it has a tunnel though, but maybe it gets not recognized or has not been precalculated)

Thanks for adding the preset. Could the server providing the tunnel data set the CORS headers so the data can be retrieved from other origins.

Access to fetch at 'https://channelsdb2.biodata.ceitec.cz/api/channels/pdb/3pqr' from origin 'http://127.0.0.1:1338' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Nice work and thanks for sharing this with the community as an extension @vDusky!
