map_auto_expan_sym (boolean, default: on) When map_auto_expand_sym is on, symmetry operations will be applied to expand it beyond the precalculated volume when necessary. Symmetry information is taken from the molecular selection if available, or from the map object, if available.

normalize_ccp4_maps (boolean, default: on) controls whether or not CCP4 maps are automatically normalized upon loading.

normalize_grd_maps (boolean, default: off) controls whether or not GRD maps are automatically normalized upon loading.

normalize_o_maps (boolean, default: on) controls whether or not O maps are automatically normalized upon loading.

swap_dsn6_bytes (boolean, default: on) controls whether or not dsn6 maps are automatically byte swapped.

default_2fofc_map_rep (string, default: volume) This controls the default map representation when a 2FoFc map is loaded from an MTZ map.

default_buster_names (string, default: 2FOFCWT PH2FOFCWT FOFCWT PHFOFCWT) This is the list of valid column names to be sought when autoloading Buster maps.

default_fofc_map_rep (string, default: volume) This controls the default map representation when a FoFc map is loaded from an MTZ map.

default_phenix_names (string, default: 2FOFCWT PH2FOFCWT FOFCWT PHFOFCWT) This is the list of valid column names to be sought when autoloading Phenix maps.

default_phenix_no_fill_names (string, default: 2FOFCWT_no_fil PH2FOFCWT_no_fill None None) This is the list of valid column names to be sought when autoloading Phenix (no fill) maps.

default_refmac_names (string, default: FWT PHWT DELFWT PHDELWT) This is the list of valid column names to be sought when autoloading Refmac maps.
