I mean, if I have 3 models in the model panel and I only want to calculate the clashes between the models 1 and 2 without close the model 3, what I have to do?
With either the graphical interface of Find Clashes/Contacts or the command findclash, you can specify which two groups of atoms to examine for clashes. The remaining atoms will be ignored. I believe it doesn't matter whether the atoms are displayed or active. With the command, it would be something like
findclash #1 test #2 [other options]
findclash ligand overlap -0.4 hb 0 test aromatic
Use command "help findclash" to see the manual page, or view it here:
With the GUI, the procedure is slightly different: you would select one group (say #1), click Designate, choose option "second set of designated atoms", select the second group (say #2), click "Designate selection as second set", Apply. Click the Help button to see the manual page, or view it here:
This is more of a chimera-users at cgl.ucsf.edu question (how to use Chimera) than chimera-dev (programming related to Chimera), so I'm also CC-ing the former list.
I hope this helps,
