Show connections in two difference files about ngl HOT 4 CLOSED

It's not possible at the moment to create either a covalent bond nor a contact between atoms from different file.
There is a request made to be able to compute contacts (non-covalent interactions) between different entities, which has implications like docking.
In the meantime, if you want to display such bonds, you may create the corresponding cylinder representations "manually" using the coordinates of the terminal atoms.

I'm found this code example:

Is this method wrong?

I was not aware of this concatStructure method. This is brilliant!
I suppose the issue might come if you want to compare different ligands docked to the same receptor. But as it is, that's very convenient

Aside: For viewing interactions for docking results (for example) you can set the masterModelIndex parameter so that interactions are only calculated between each model and the 'master' (so if protein is model 0, then each ligand model 1.. you don't get interactions between different ligand poses). https://github.com/nglviewer/ngl/blob/master/examples/scripts/test/concat.js#L14
