PDB CD-ROM Set 93 Released

The PDB archive was released on this quarter's CD-ROM set 93.

The CD-ROMs contain the full release of PDB structure files, structure factor files, NMR constraints and some contributed software and resources. The structure of the directories is that of earlier CD-ROM's; two directory names were changed with the April 2000 release. Distr was replaced by Entries and Nonst by Strucfac.

The current CD-ROM set includes the 12,592 structures as of the update on June 28, 2000. Five CD-ROMs are required to contain these structures in compressed (gzip) format. The next CD-ROM set, the October 2000 release, will include the 13,270 structures as of the update on September 27, 2000.

The PDB releases these CD-ROMs on a quarterly basis, at no cost.
