PDB File Format FAQ Available

The PDB has released a document that addresses questions about the PDB file format frequently posed by depositors and users over the past year. The File Format FAQ at http://pdb.rutgers.edu/format-faq-v1.html compiles information from the PDB Contents Guide document originally created at Brookhaven National Laboratory, a careful study of existing files, an RCSB Workshop held in October 1998, and discussion with many users of the data. The guidelines presented here are those used by the annotation staff at the RCSB PDB. Questions not addressed in this document should be sent to deposit@rcsb.rutgers.edu.
