CIFTr and Data Uniformity Files Released

An application program that can translate files between mmCIF format and PDB formats has been released. Called CIFTr, this program 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 (see Message from the PDB for more information). These files (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 at http://www.rcsb.org/pdb/uniformity/.

CIFTr works on UNIX platforms and can be downloaded at http://pdb.rutgers.edu/software/. Questions about this program may be sent to info@rcsb.org.
