There is a new version of the CRAD utility program in place. There has been a certain amount of restructuring of the program code, but users should not detect any significant differences other than tidying of the output format. The old version of the program is still available as ocrad . A utility to symmetry expand the set of coordinates from a .xr file to fill the unit cell. This is useful for structures extracted from CSSR , ICSD or MDF that you wish to view with rasmol .
Online documentation is available.
