[Chimera-users] combining mrc maps

[Elaine Meng]

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
