| # Dataset Name | |
| JARVIS MEGNet2 | |
| ### Description | |
| The JARVIS-MEGNet2 dataset is part of the joint automated repository for various integrated simulations (JARVIS) database. This subset contains 133K materials with formation energy from the Materials Project, as used in the training of the MEGNet ML model. JARVIS is a set of tools and datasets built to meet current materials design challenges. | |

| # 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). | |
