[PyMOL] Differentiate between bond types by color and representation

[Lorenzo G. <br...@gm...>]

Dear pymol users,

I'm trying to properly represent a coarse-grained protein model that has an
elastic network.

I would like to show the bonds that are part of the elastic network with a
different color (and possibly representation) from the normal bonds between
atoms. However, as far as I know, color settings are atom-based, so I
wasn't able to do what I wanted, because all bonds that lead to an atom
will always share the same color.

The only solution I found was to create a copy of the protein with
pseudoatoms and draw the elastic network there. However, I expect this has
a negative effect on the performance, which is relevant since I plan to use
this for molecular dynamics trajectories.

Am I trying to do this the wrong way? Is it just unfeasible?
