PDBFixer is an application for fixing problems in Protein Data Bank files in preparation for simulating them. It can automatically fix the following problems:

- Add missing heavy atoms. - Add missing hydrogen atoms. - Build missing loops. - Convert non-standard residues to their standard equivalents. - Select a single position for atoms with multiple alternate positions listed. - Delete unwanted chains from the model. - Delete unwanted heterogens. - Build a water box for explicit solvent simulations.

This package installs the library for Python 3.
