GRIP-Tomo: GRaph Identification of Proteins in Tomograms

A pipeline to help identify and classify structures in tomography data using global and local topological (network) features.

The package consists of 3 core modules:

1. pdb2graph.py - converts a PDB structure into a graph network.
2. density2graph.py - converts a 3D density to a graph.
3. graph2class.py - measures graph features and classifies
