simplemmtf is a lightweight MMTF encoding and decoding module written in Python. It was originally developed for PyMOL 1.8.4 to prototype MMTF load support.

This implementation is similar (but unrelated) to mmtf-python.

• msgpack-python or u-msgpack-python
• numpy (optional)

• mmtf2cif.py: Convert MMTF to mmCIF (without bonds)
• pdb2mmtf.py: Convert PDB to MMTF (without bonds)
• pymol_get_mmtfstr.py: Register MMTF export with PyMOL 1.8.6
