RSPS version 4.0: : a semi-interactive vector-search program for solving heavy-atom derivatives

• A program for inspection and interpretation of the Patterson function is described. The program is mainly intended for finding heavy-atom positions from difference Patterson maps, but may also be used to locate molecules with non-crystallographic symmetry when the local axis is nearly parallel to a crystallographic symmetry axis. Options are available for vector-based methods to locate heavy-atom sites, for finding sets from a list of possible heavy-atom positions and for checking of potential solutions. Both crystallographic and non-crystallographic symmetry may be used, either independently or in conjunction.
