I installed mapman and it's also failed with similar error when trying to convert with mapman. See below:MAPMAN > re slot1 sa_omit_map.map Format ? (CCP4) XPLOR
Try format "CNS" or "X-PLOR" and as I asked earlier what does "head sa_omit_map.map" or the head output from your map file you tried to load in coot show?
