What problem does it solve?
Pymatgen provides a comprehensive toolkit for researchers to create, analyze, and transform crystal structures, perform format conversions, analyze symmetry, build phase diagrams, study electronic structures, and access Materials Project data programmatically.
Core Features & Use Cases
- Structure creation and manipulation: build or modify crystal structures and molecules, export to multiple formats, and perform transformations.
- File I/O & format conversion: read/write 100+ file formats, enabling interoperability across codes and workflows.
- Symmetry & structure analysis: determine space groups, lattice parameters, and coordination environments to simplify analyses.
- Phase diagrams & thermodynamics: construct phase diagrams, evaluate stability, and explore decomposition pathways.
- Electronic structure analysis: analyze band structures and DOS, and integrate with VASP and other codes.
- Surfaces, interfaces, and high-throughput workflows: generate slabs, study surfaces, and drive large-scale computational workflows with Materials Project data.
- Materials Project integration: programmatic access to materials data for screening and phase-space exploration.
Quick Start
Install pymatgen and optional dependencies, then run the included scripts to analyze structures, generate phase diagrams, and perform electronic-structure workflows.
