Hi Lothar, In Chimera, it is command "vop zone" with invert true: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/vop.html#zone> ChimeraX also has this feature, as "volume zone" (with invert true, newMap true): <http://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#zone> I hope this helps, Elaine ----- Elaine C.

Hi, I am sure this is possible I just could not find it in the documentation: Can someone quickly remind me how to subtract density that surrounds a molecule so as to leave the extra density in the map ? Volume eraser seems to use a sphere but this is too crude. I am interested in an extra domain that is not (yet) in my model and it would help to remove the portion that I know from the density. There is probably a very simple solution that I just can’t seem to find. Thanks, Lothar
