Hi Alexis, I can reproduce the problem with reading the pb file transparency using a color specification of the form: /a:1@c3' /a:1@n3 rgba(20,90,90,70) However, if I use these alternative forms of transparent color specification, it works, i.e. the pseudobond is transparent: /a:1@c3' /a:1@n3 20,90,90,70 - OR - /a:1@c3' /a:1@n3 #00ced155 <http://rbvi.ucsf.edu/chimerax/docs/user/commands/colornames.html> Those atoms are in PDB 1bna, for example. Tested in current daily build I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Thanks Elaine!
Great - so now I'm using "measure center" to create markers with 0.0000001 radius at the center of my rings with specified modelId's. Then I have a .pb file that specifies the pseudobonds to draw between markers and atoms. That all seems to work pretty well, thanks!
Only little snag right now is I can't seem to get transparency working when the color-spec in the .pb file is in the format rgba(). Setting the transparency after opening the pb file using "transparency" works fine though, so I'm not stuck.
Thanks again for the help.
Cheers, Alexis
