# Dataset Name |
|
|
ANI-1 |
|
|
### Description |
|
|
ANI-1 is a dataset of 20 million conformations with calculated non-equilibrium energy values. The conformations are based on a subset of the GDB-11 dataset, each molecule containing between 1 and 8 heavy atoms, with atomic species limited to C, N and O. Configuration sets are included for standard and high energy (defined as energies greater than 275 kcal*mol-1 higher than the lowest energy conformer) conformations, and, within these, number of heavy atoms per molecule. |

# 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). |
