I need to change the center of rotation at every frame.

I am using

from chimera import viewer

cam = chimera.viewer.camera

cmd = 'cofr fixed %s,%s,%s' %(cam.eyePos(0))

chimera.runCommand(cmd)

which generates a message in the reply log

Center of rotation: 564.31 -345.208 699.718

How can I disable this message in the reply log?

Or is there another method I should use (eg, hack the cofr command)?
