Protein Data Bank CD-ROM News

First Update Release

The April 2003 release of the PDB CD-ROM sets, issue 104, is an incremental set of 1,317 experimentally determined structures and 23 models. The structures, on one CD-ROM disk, have been shipped.

Structures re-released for any reason between January and April are included in this update. A list of files that have become obsolete since the last update are included so users can update their set of structures.

July and October issues will only contain the structures released during those quarters. New subscribers will receive the January release and all subsequent updates.

Experimental data - NMR constraints and X-ray structure factors - will be handled in the same manner as the structures - a complete set in January, and incremental updates for the three subsequent quarters. New subscribers will receive the January release and all updates.
