Hi, minor suggestion for Chimera, related to dealing with large numbers of maps: It would be really helpful if there was a 'Save map' dialog in the 'File...' menu, with similar dropdown menus to select the map one wants to save as for the 'Save PDB' dialog. Doing so via the volume viewer is a bit clunky when there are lots (e.g. 10+) of maps loaded. Even better would be if it included a 'Save relative to map' dropdown, analogous to the 'Save relative to model' drop down in the 'Save PDB' dialog, which would resample the map to be saved on the grid of the selected target map (perhaps warning of the potential for a modest loss of quality). This would be really helpful when one aligns many different conformations of a molecule (e.g. from 3D classification) to a reference subvolume and wants to save the resulting transformed maps. Cheers, Oli.
