Crystallographic Information Framework



The ISTable package is a collection of classes for managing table objects. This class provides the foundation for many PDB applications which parse, search and manage mmCIF data and dictionaries. This class uses an improved indexing scheme relative to its predecessor class SSTABLE. The package is also known as CIFTable.

Language and platform

The software is written in C++ and should run on versions of Unix with suitable C++ compilers.


  • Installation: For Unix-type installations, copy the gzipped tar file cif-table-obj-v8.011-prod-src.tar.gz into an empty directory; ungzip and extract files using the Unix tar utility. Build the application using the make utility; run the test program with 'make test':
     cp cif-table-obj-v8.011-prod-src.tar.gz /g/h/i; cd /g/h/i
    gunzip cif-table-obj-v8.011-prod-src.tar.gz; tar xvf cif-table-obj-v8.011-prod-src.tar
    cd cif-table-obj-v8.011-prod-src
    make test
    If gzip or tar are unavailable, individual source files may be saved to the build directory.
