PDB Focus: CIFTr

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 ftp://beta.rcsb.org/pub/pdb/uniformity/data/mmCIF/. Further information about the Data Uniformity project is accessible at http://www.rcsb.org/pdb/uniformity/.
