# Dataset Name
OC20 S2EF val id
### Description
OC20_S2EF_val_id is the ~1-million structure in-domain validation set of the OC20 Structure to Energy and Forces (S2EF) dataset. Features include energy, atomic forces and data from the OC20 mappings file, including adsorbate id, materials project bulk id and miller index.

# 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).
