# Dataset  Name  
OMol25 train  
### Description  
The full-size training set from OMol25. From the dataset creator: OMol25 represents the largest high quality molecular DFT dataset spanning biomolecules, metal complexes, electrolytes, and community datasets. OMol25 was generated at the ω B97M-V/def2-TZVPD level of theory.

# 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).
