[Chimera-users] Displaying Labels without displaying Atoms

Hi Nicholas,
Several pseudobond “attributes” like whether they depend on atom display and their linewidth, color, label text etc. can be controlled with the “setattr” command.  Some of the attributes are at the level of the pseudobond group, such as all distance measurements, whereas others can be changed for individual pseudobonds.   How you can tell which of those applies and the name of the attribute for use with the “setattr” command is by selecting any pseudobond, showing the Selection Inspector (e.g. by clicking the green magnifying glass icon at the lower right corner), and then mousing over the entries in the dialog when inspecting “pseudobond”  or “pseudobond group.”  The pop-up balloon help will give the attribute name and some information about its possible values. Or instead of in the Selection Inspector, this lookup can also be done in the pseudobond group attributes dialog opened with the “attributes…” function in the Pseudobond Panel  (menu:  Tools… General Controls… Pseudobond Panel).

I gave you the long answer above so you could understand how to change several things about pseudobonds with “setattr” …. the short answer is  a command something like:

setattr p display 1

… as shown in the aforementioned balloon help, 1 is displayed, 0 is hidden, 2 is conditional on atom display.

I hope this helps,
Elaine
