[Chimera-users] Q about opening two structures in the same window

[Elaine Meng]

Hi Farhana,
You can open several different structures from different files and  
display them all in the same window.  It sounds like you figured that  
part out already.

Then you can freeze/freeze structures (we call that "activation" and  
"deactivation" for motion) so that only the active ones can be moved  
with the mouse.  Activation/deactivation can be controlled in several  
ways:

   - checkboxes under the Command Line (show with Favorites... Command  
Line)
   - Model Panel (Favorites... Model Panel), checkboxes in the Active  
column and/or various "activate" function buttons on the right
   - with the "select" command

See <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/mouse.html#activedef 
 >

Or if you are moving structures with commands, in newer versions of  
Chimera (1.4, so daily builds), you can specify which models you want  
to move.  Movement commands include "move" (translation) and  
"turn" (rotation).

I hope this helps,
Elaine
