Library for macromolecular crystallography and structural bioinformatics. For working with coordinate files (mmCIF, PDB, mmJSON), refinement restraints (monomer library), electron density maps (CCP4), and crystallographic reflection data (MTZ, SF-mmCIF). It understands crystallographic symmetries, it knows how to switch between the real and reciprocal space and it can do a few other things.

This package contains main gemmi executable.
