[Chimera-users] Save multiple fitted maps in Chimera

Thank you so much for your quick reply. The ChimeraX is much faster than Chimera. With vol resample, I was able to get the new individual map on fitted positions.
BTW, for any other user's future reference, Clara Altomare pointed out the following command could add multiple density map together: vop add #1-99

If you use ChimeraX instead (which has the same fitting capabilities), saving a ChimeraX session has an option to include density maps in the file. However, it sounds like that might be an extremely huge file, perhaps impractically large.
In general, however, ChimeraX is much better/faster for working with large data than Chimera.
