macromolecular structures as pandas DataFrames

MacroMolecular DataFrames (mmdf)

MacroMolecular DataFrames (mmdf) is a small package for reading macromolecular structure files (.pdb/.mmCIF) into pandas dataframes.

The heavy lifting of reading structure files is performed by gemmi.

Usage

import mmdf

df = mmdf.read('4v6x.cif')
df.head()
