$ gemmi sf2map -h
Usage:
gemmi sf2map [options] INPUT_FILE MAP_FILE
INPUT_FILE must be either MTZ or mmCIF with map coefficients.
By default, the program searches for 2mFo-DFc map coefficients in:
- MTZ columns FWT/PHWT or 2FOFCWT/PH2FOFCWT,
- mmCIF tags _refln.pdbx_FWT/pdbx_PHWT.
If option "-d" is given, mFo-DFc map coefficients are searched in:
- MTZ columns DELFWT/PHDELWT or FOFCWT/PHFOFCWT,
- mmCIF tags _refln.pdbx_DELFWT/pdbx_DELPHWT.
Options:
-h, --help Print usage and exit.
-V, --version Print version and exit.
-v, --verbose Verbose output.
-d, --diff Use difference map coefficients.
--section=NAME MTZ dataset name or CIF block name
-f COLUMN F column (MTZ label or mmCIF tag).
-p COLUMN Phase column (MTZ label or mmCIF tag).
--weight=COLUMN (normally not needed) weighting for F.
-g, --grid=NX,NY,NZ Grid size (user-specified minimum).
--exact Use the exact grid size specified by --grid.
-s, --sample=NUMBER Set spacing to d_min/NUMBER (3 is usual).
--zyx Output axes Z Y X as fast, medium, slow (default is X Y
Z).
-G Print size of the grid that would be used and exit.
--timing Print calculation times.
--normalize Scale the map to standard deviation 1 and mean 0.
--mapmask=FILE Output only map covering the structure, similarly to CCP4
MAPMASK with XYZIN.
--margin=N (w/ --mapmask) Border in Angstrom (default: 5).
--select=SEL (w/ --mapmask) Selection of atoms in FILE, MMDB syntax.
