Hi Alexis, The pseudobond reader could be improved to set the dashes. But all the pseudobonds in a pseudobond model must have the same number of dashes. So your example of setting 2 different dashes values in the file won't work. Tom

Well, it's good to know I'm the only one who sometimes fails to RTFM :)
While we're on the topic of pb files, I was hoping to play with the number of dashes (since the last line of the doc for pbfiles mentions a default dashes of 8), but I guess this is not something that can be set in the pb file? I was trying something like this:
; pseudo bonds for figure ; radius = 0.05 ; dashes = 3 #1/L@H42 #1/B:940@OE1 rgba(12,56,100,0.2) #1/L@O11 #1/A:840@HH dodgerblue #1/B:940@HE21 #1/B:887@OG dodgerblue ; dashes = 8 #10841 #1/A:840@CD2 yellow #10884 #1/A:840@CE1 yellow #10840 #1/B:940@HE22 yellow #10001 #1/B:947@CZ yellow #10002 #1/A:841@CZ yellow

When using the rgba(N,N,N,N) form only the first three numbers can be whole numbers in the range 0-255, or percentages indicated with % symbols, which I failed to do. The transparency number has to be in the range 0-1.
So you would need something like the following, which also works. Tested in daily build and in release 0.92.
rgba(20%,90%,90%,0.7)
Sorry for the mistake -- I normally use the simpler form: 20,90,90,70 Elaine

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

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
