[Chimera-users] Creating and visualizing a plane

I'm not sure if this is a function available in Chimera. I have a protein system with three residues which define a plane, or floor, relative to an active site. I would like to display a translucent plane passing through the alpha carbon of these three residues to shoot an image. Further, I would like to quantify deviation of mobile regions relative to this plane. Thanks, Jim ________________________________________________________ James Nettles, Ph. D.
