A preliminary version of cif2pdb, a ciftbx2 application to convert mmCIF entries to a pseudo-PDB format is available from http://ndbserver.rutgers.edu/software on the ciftbx page via the link LINK_TO_cif2pdb This program is a preliminary version capable of doing a conversion of an mmCIF data set to a partial pseudo-PDB entry with HEADER, TITLE, COMPND, SOURCE, SEQRES, CRYST1, ORIGX, SCALE, ATOM, HETATM, MASTER and END records. This is sufficient to drive RASMOL. We hope to add most of the remaining record types by June 96. Comments to yaya@aip.org appreciated. -H. J. Bernstein and F. C. Bernstein
