CIFTr is an application program that translates files in mmCIF format
into files in PDB format. CIFTr works on UNIX platforms, and can be
downloaded at http://pdb.rutgers.edu/software/.
CIFTr also provides the option of producing a file with a blank chain ID field for
structures with a single chain, and the option of producing files with
standard IUPAC hydrogen nomenclature for standard L-amino acids.
CIFTr was released this summer along with the files from the Data
Uniformity Project. These files, available in mmCIF format, can be
accessed from the PDB beta FTP site at
