# Dataset Name
COLL test
### Description
Test set from COLL. Consists of configurations taken from molecular collisions of different small organic molecules. Energies and forces for 140,000 random snapshots taken from these trajectories were recomputed with density functional theory (DFT). These calculations were performed with the revPBE functional and def2-TZVP basis, including D3 dispersion corrections

# 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).
