Hi Jeff, It's not a bug. You would need to specify the selected atom as the argument to "cofr", for example: cofr sel If you type only "cofr" without arguments it merely reports the location of the current center of rotation and doesn't change it. http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/cofr.html Best, Elaine ----- Elaine C.

hi Elaine,
I just loaded a pdb, selected an off-center atom, typed 'cofr' at commandline, and the cofr does not appear to change (rotation looks the same in the chimera window). I submitted a bug report,
