pymatgen

# Pymatgen - Python Materials Genomics ## Overview Pymatgen is a comprehensive Python library for materials analysis that powers the Materials Project. Create, analyze, and manipulate crystal structures and molecules, compute phase diagrams and thermodynamic properties, analyze electronic structure (band structures, DOS), generate surfaces and interfaces, and access Materials Project's database of computed materials. Supports 100+ file formats from various computational codes. ## When to Use This Skill This skill should be used when: - Working with crystal structures or molecular systems in materials science - Converting between structure file formats (CIF, POSCAR, XYZ, etc.) - Analyzing symmetry, space groups, or coordination environments - Computing phase diagrams or assessing thermodynamic stability - Analyzing electronic structure data (band gaps, DOS, band structures) - Generating surfaces, slabs, or studying interfaces - Accessing the Materials Project database programmatically - Setting up high-throughput computational workflows - Analyzing diffusion, magnetism, or mechanical properties - Working with VASP, Gaussian, Quantum ESPRESSO, or other computational codes ## Quick Start Guide ### Installation ```bash # Core pymatgen uv pip install pymatgen # With Materials Project API access uv pip install pymatgen mp-api # Optional dependencies for extended functionality uv pip install pymatgen[analysis] # Additional analysis tools uv pip install pymatgen[vis] ...
