I'm returning to chimera after many years away and am quite impressed with the program, save for one issue: rotating about the screen center. My favorite way of viewing structures is for the rotation to be about a center of my choosing, as is common in many graphics programs (e.g. COOT). I would prefer to pick an atom on the screen and have this become the rotation center. Is there a simple way to accomplish this in chimera? A small point perhaps, but one that is frustrating for me....... Bill Montfort
Hi Bill, You can use the command "cofr" with specified atoms (including "sel" as the specification if the atom or atoms are selected). <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/cofr.html> There are several different rotation modes, and you can switch among them using either "cofr" or the Rotation tool (under Tools... Movement in the menu). <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/sideview.html#rotation> I hope this helps, Elaine ----- Elaine C.

Alternatively, you can control-click on the atom to select it and then choose Actions->Set Pivot in the menus to make it the center of rotation. --Eric Eric Pettersen UCSF Computer Graphics Lab On Dec 30, 2010, at 9:51 AM, Elaine Meng wrote:
