Hi Martin, Chimera doesn't have a way to add maps yet. The volume operation, vop, command would be the logical place to support that. A command like "vop #0 add #1 extend true sample true multiplier 0.25" could be implemented to add two maps extending the grid of first map #0 to cover the second and sampling the second map values (since its grid points won't generally align with those of the first map's grid) and scale the second map to allow getting comparable normalizations. I'll add this to the feature request list. Tom Martin Kampmann wrote:
Hello,
I just downloaded the new Chimera version and tried to combine different models (density maps) into one volume, using the new 'combine' function, (e.g. combine #1 #2), but it returned an error message.
Is it only possible to combine atomic structures (such as PDB files), or is there a way to combine volumes/density?
Thanks a lot! Martin
P.S.: Thank you so much for developing Chimera! I enjoy working with this program a lot!
