Coot

This is a program for constructing atomic models of macromolecules from x-ray diffraction data. Coot displays electron density maps and molecular models and allows model manipulations such as idealization, refinement, manual rotation/translation, rigid-body fitting, ligand search, solvation, mutations, rotamers. Validation tools such as Ramachandran and geometry plots are available to the user. This package provides a Coot build with embedded Python support.
