A pure Python module containing tools for crystallography and single-particle cryo-EM.
Contains functions for cutting density out of cryo-EM maps and calculating structure factors
Contains functions for reading and writing maps, map coefficients, model coordinates, and structure factors
A number of useful functions, including:
- Needleman-Wunsch algorithm for pairwise sequence alignment
- B-factor analysis
- Ramachandran validation
- Amino acid atomic geometry validation
- Mainchain and sidechain torsion angle calculators
Contains functions that make it easy to do molecular replacement with cryo-EM maps
