5.13. MMTF Topology Parser

Reads topology data from the Macromolecular Transmission Format (MMTF) format. This should generally be a quicker alternative to PDB.

Makes individual models within the MMTF file available via the models attribute on Universe.

New in version 0.16.0.

Changed in version 0.20.0: Can now read files with optional fields missing/empty

Changed in version 2.0.0: Aliased bfactors topologyattribute to tempfactors. tempfactors is deprecated and will be removed in 3.0 (Issue #1901)

Reads the following topology attributes:

Atoms:

• altLoc
• atom ID
• tempfactor
• bonds
• charge
• masses (guessed)
• name
• occupancy
• type

Residues:

• icode
• resname
• resid
• resnum

Segments:

• segid
• model
