pycell
PyMOL plugin that can draw supercells on each frame from a pdb trajectory. Currently it has been tested you PDB files created with GROMACS and Materials Studio. The cell is drawn following the convention, A along X, B in YX plane. Pycell requires that each PDB model have the CRYST1 field. Also the NumPy package for python is needed.
Use in pymol commandline as: pycell_trajectory /my/path/to/file/test.pdb
Tested with python 2.7.6 GROMACS 5.1.1 PyMOL 1.7.4.5 Edu Materials Studio 6.0
