| # Dataset Name |
| MatPES-R2SCAN-2025.2 |
| ### Description |
| MatPES (Materials Potential Energy Surface) is a foundational PES dataset developed collaboratively by the Materials Virtual Lab and the Materials Project. The v2025.2 r2SCAN release contains 386,544 structures sampled via the DIRECT method from 300 K NpT molecular dynamics simulations seeded from Materials Project entries. Static DFT calculations were performed using VASP with the r2SCAN meta-GGA functional and MatPESStaticSet convergence settings optimized for energy, force, and stress calculations. v2025.2 removes a small number of duplicated structures present in v2025.1, and the original files add Bader charges and Bader magnetic moments per atom. The previous version of this dataset (MatPES-R2SCAN-2025.1) is available from ColabFit. There is a companion dataset calculated with the PBE functional (MatPES-PBE-2025.2). |

| # Usage |
| - `ds.parquet` : Aggregated dataset information. |
| - `co/` directory: Configuration rows each include a structure, calculated properties, and metadata. |
| - `cs/` directory : Configuration sets are subsets of configurations grouped by some common characteristic. If `cs/` does not exist, no configurations sets have been defined for this dataset. |
| - `cs_co_map/` directory : The mapping of configurations to configuration sets (if defined). |
