# Dataset  Name  
W PRB2019  
### Description  
This dataset was originally designed to fit a GAP potential with a specific focus on properties relevant for simulations of radiation-induced collision cascades and the damage they produce, including a realistic repulsive potential for short-range many-body cascade dynamics and a good description of the liquid phase.

# 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).
