Hi Daniel, You can add or subtract maps to make a new map using the "vop" command: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/vop.html> That command has various other filtering and scaling options that may also be of interest. You can save the new map to a file using the Volume Viewer dialog (its File menu) or the "volume" command. I hope this helps, Elaine ---------- Elaine C.

Hi, I was wondering if it is possible to combine two mrc volumes into a single volume and save that as a new mrc file? I haven't really been able to find anything and I suspect that this may not be possible with Chimera. Thank you for your help, Daniel
