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

[Elaine Meng]

Hi Francesco,
I'm not sure I understand what you are asking.  Maybe you are saying that when you hide a model, the centroid is also hidden?

Instead of hiding the model with the Model Panel "Shown" checkbox or command "~modeldisplay", which hides everything in the model, you can undisplay the protein parts and leave the centroid displayed.  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:

~display #0
~ribbon #0
~surf #0

(commands to undisplay atoms/bonds, ribbon, and molecular surface of model #0).  Then, you would have the protein #1 plus the centroids of both #0 and #1 displayed.  I hope this helps,
Elaine
