Generates the crystal packing of a PDB protein.
It is possible to inspect it immediately with the visualize option. It can only be generated if there is crystallographic information in the PDB entry.
pdbid (str) – ID from the Protein Databank
hexagonal (bool) – # TODO: Undocumented
visualize (bool) – If True, this function also visualizes the crystal packing
VMD object, optional) – A specific viewer in which to visualize the molecule. If None it will use the current default viewer.
mol – Molecule object with the crystal packing
