Tool for the ab-initio generation of a SHELXL-97 'List 4' style FCF file based on the coordinate data supplied in a '.res' or '.cif'.
Note: 'Fobs' and 'Fcalc' are necessarily equal to Fcalc in this file with extension '.hkp'.
Alternative Keyboard Instruction:
CALC FCF GENERATE
Wavelength CuKa = 1.5418 Ang is assumed when none is given.
Warning: This option should not be confused with the CALC FCF option to produce a SHELXL-97 'List 4' style from a '.res' and a '.hkl' file (Generally needed after a SQUEEZE based refinement).
