Hi all, RIght now, if you do "Actions->Atom/Bonds->backbone only" Chimera shows the minimum number of atoms to produce a connected peptide/ nucleic acid backbone, which therefore does not include peptide carbonyl oxygens nor nucleic sugar rings/charged phosphate oxygens. We are thinking of changing the behavior so that "backbone only" includes everything that isn't in the side chain/base. The question is: does anyone need/want the current behavior? If not, I'd not only change "backbone only" but would also change Select->Structure-
backbone from a menu (has "full" and "minimal" in it) to just a menu item that selects the full backbone. If there are some people who do use the current behavior, then instead I'd change "backbone only" to be a menu too.

It is a nice feature to have a quick button to grab just C,CA,N atoms. Although, one could make the argument that a short Chimera script would work just as well or better for customization. I am thinking of teaching new students about molecular graphics and not sure if I'd like to lose the backbone minus CO oxygen option.
