[Chimera-users] Showing more than a single centroid trace

[Elaine Meng]

Hi Francesco,
You cannot select centroid objects with a command -- they do not have residue or atom names.  You can only select them by clicking their lines in the Axes/Planes/Centroids dialog, or by Ctrl-clicking on them in the Chimera graphics window.

For example, if I had protein models #0 and #1 and also centroids for each of those, I could undisplay the protein part only of #0:
