[Chimera-users] 3D dashed pseudobond styles?

Hi all,

Feature request - more 3D psuedobond styles (for missing segments and metal coordination) would be nice. Specifically, small spheres (3D equivalent of dotted line) and cylinders with either rounded or flat ends (3D equivalent of dashed lines) would be very helpful.

Often when used in combination with 3X3 or 4X4 supersampling, pseudobonds drawn in wire representation become too thin to see, whereas this is not the case for bonds or other 3D elements of the structure. Normally this doesn’t matter, because I can just redraw these bonds in a vector graphics program, but for stereo figures this doesn’t work. There is already one such option (representing pseudo bonds as sticks), but this looks weird - dashing or dotting is I think desirable to avoid confusion with regular bonds.

Also, is there any way to add a custom pseudo bond (not a distance, no label) between a single pair of selected atoms? Similar to the dist command? This would be very helpful, for example, when trying to highlight a handful of specific interactions of a ligand with active site residues.

One more while I’m thinking of it - a bit out there and certainly not for chimera 1 - it would be great  to have a way of arranging 3D labels for residues such that they are displaced from the structure (perhaps arranged in a circle on the x-y plane), but with lines or arrows connecting them back to the residues they are labeling - this would be particularly great for generating labeled stereo figures, which is otherwise hard to do.
