pdb-tools: a swiss army knife for molecular structures [version 1; peer review: 2 approved]

The pdb-tools are a collection of Python scripts for working with molecular structure data in the Protein Data Bank (PDB) format. They allow users to edit, convert, and validate PDB files, from the command-line, in a simple but efficient manner.
