vcif version 0.58


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

The MS-DOS version is not currently under active maintenance.

Language and platform

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.


  • Installation: Copy the compressed tar file vcif.tar.Z into an empty directory; uncompress and extract files using the Unix tar utility. Then use the make utility to build the application:
     cp vcif.tar.Z /a/b/c; cd /a/b/c
    uncompress vcif.tar.Z; tar xvf vcif.tar
    If compress or tar are unavailable, individual source files may be saved to the build directory.
