Pymatgen IO (Non-VASP)
Overview
Pymatgen IO (non-VASP) handles file formats and interfaces for many DFT/MD codes other than VASP.
Required Python Environment
Ensure pymatgen is installed in your Python environment:
pip install pymatgen
conda install -c conda-forge pymatgen
Example usage pattern:
from pymatgen.io.cif import CifParser
When to Use This Skill
- Parse or write CIF, XYZ, Gaussian, or related formats
- Interface with CP2K, QE, Q-Chem, ABINIT, LAMMPS, FEFF, NWChem, etc.
Core Capabilities
1. Common Formats
- CIF, XYZ, Gaussian, and adapters (ASE/OpenBabel if installed)
2. Code Interfaces
- Q-Chem, CP2K, Quantum ESPRESSO, ABINIT, LAMMPS, FEFF
3. Conversion
- Convert external formats to
Structure/Molecule
Quick Workflow
- Identify the input/output format or code interface.
- Parse into
Structure or Molecule objects.
- Write converted outputs or parse results.
