PDBFixer automatically fixes problems in Protein Data Bank (PDB) files. It addresses common issues that arise when preparing structures for molecular simulations. The tool focuses on automatically correcting structural inconsistencies, ensuring the PDB file is suitable for use in computational studies. It leverages a suite of algorithms tailored for PDB file manipulation.
PDBFixer provides a comprehensive set of automated fixes for common PDB file errors, simplifying the preparation workflow. The tool supports multiple functionalities in a single program, reducing the need for separate tools. It is designed for ease of use, requiring minimal user intervention for common corrections.
- Atom Addition: Adds missing heavy and hydrogen atoms to PDB files.
- Loop Building: Builds missing loops in protein structures.
- Residue Conversion: Converts non-standard residues to standard equivalents.
- Atom Selection: Selects a single position for atoms with multiple alternate positions.
- Chain/Heterogen Deletion: Removes unwanted chains and heterogens from models.
- Water Box Generation: Builds a water box for explicit solvent simulations.
- Installation: Easily installable via conda or from source.
