The macromolecular transmission format (MMTF) is a binary encoding of biological structures.

This repository holds the Java API, encoding and decoding libraries. Along with a description of the data in the MMTF using Java data types.

Releases are available on Maven central.

Quick getting started.

1. Get the data for a PDB structure and print the number of chains:

StructureDataInterface dataInterface = new GenericDecoder(ReaderUtils.getDataFromUrl("4CUP"));
System.out.println("PDB Code: "+dataInterface.getStructureId()+" has "+dataInterface.getNumChains()+" chains");

2. Show the charge information for the first group:

System.out.println("Group name: "+dataInterface.getGroupName(0)+" has the following atomic charges: "+dataInterface.getGroupAtomCharges(0));

3. Show how many bioassemblies it has:

System.out.println("PDB Code: "+dataInterface.getStructureId()+" has "+dataInterface.getNumBioassemblies()+" bioassemblies");
