The Pdb Extract Program Suite contains tools and examples for extracting mmCIF data from structure determination applications. Note: Binary distribution of this tool contains an additional submodule "procheck", which does additional structure checking. This submodule is not part of the source distribution. Therefore the users are advised to use the binary distribution, if possible. Refer to README-source or README-binary, depending on the distribution, for details on installation, build, demos and application usage.
