The **m**acro**m**olecular **t**ransmission **f**ormat (MMTF) is a binary encoding of biological structures.

This repository holds the Python 2 and 3 compatible API, encoding and decoding libraries.

The MMTF python API is available from pip:
```
pip install mmtf-python
```

Quick getting started.

1) Get the data for a PDB structure and print the number of chains:
```python
from mmtf import fetch
# Get the data for 4CUP
decoded_data = fetch("4CUP")
print("PDB Code: "+str(decoded_data.structure_id)+" has "+str(decoded_data.num_chains)+" chains")
```
2) Show the charge information for the first group:
```python
print("Group name: "+str(decoded_data.group_list[0]["groupName"])+" has the following atomic charges: "+",".join([str(x) for x in decoded_data.group_list[0]["formalChargeList"]]))

```
3) Show how many bioassemblies it has:
```python
print("PDB Code: "+str(decoded_data.structure_id)+" has "+str(len(decoded_data.bio_assembly))+" bioassemblies")
```
