Section 25.2.1.13.4. Importing phase information

The program IMPORT allows users to `import' phase information obtained from programs external to the package so it can be used for subsequent calculations within the package. For example, one can use phase and probability distribution information obtained elsewhere to initiate solvent flattening, negative-density truncation and/or NC symmetry averaging within PHASES, or simply to generate and display maps with MAPVIEW or the other graphics programs. Reflection indices, the observed structure-factor amplitude, figure of merit, phase and phase probability distribution coefficients must be supplied, although free format can be used.
