Describes CIF, the data exchange standard of crystallography. Provides: information for scientists who wish to record or use the results of a single-crystal or powder diffraction experiment; the data ontology necessary for designing interoperable computer applications; accompanying software including machine-readable CIF dictionaries, libraries and utility programs.
An essential guide and reference to CIF for programmers, data managers handling crystal-structure information and practising crystallographers.
vcif is a simple syntax checker for files in CIF format, including data and dictionary files. It may be used to scan any text file and outputs informative messages about apparent errors in CIF syntax.
Version 0.58 is compatible with the CIF specification 1.0 and has some extensions allowing validation of some STAR File features found in CIF dictionary files. (This version has also been distributed as "Version 1" with International Tables for Crystallography Volume G, First Edition, 2005.) Version 1.2 (see Other versions below) supports CIF specification 1.1. Bug fixes and requests for enhancement should be directed to email@example.com.
The MS-DOS version is not currently under active maintenance.
The software is written in ANSI C and should compile and run in a command-line environment on any common operating system with an ANSI C compiler.
cp vcif.tar.Z /a/b/c; cd /a/b/cIf compress or tar are unavailable, individual source files may be saved to the build directory.
uncompress vcif.tar.Z; tar xvf vcif.tar
