Unless I'm mistaken (which is very possible), it appears that by default PyMol normalizes an input map upon loading.
I'd like to disable this feature. Looking in the menu at Settings .../Edit All ... I've found the variable normalize_ccp4_maps and changed its default value from 1 to 0 (or in a script I've added "set normalize_ccp4_maps, 0"). This does not appear to have any effect at all. Does anyone know how to disable automatic normalization of an input map? Also does anyone has a script which draws a "carved" density? I've tried to do this but without success.
