I am good with reintroducing it. Meanwhile I also would like to see a
concrete example in the Cookbook about it because I think the problem is
also to characterize the link.
I would try to start by representing what Layla outlined: a 3D version of
that image can be retrieved from “PDB link” in format “XXX”
