# Dataset Name |
|
|
Chig-AIMD random train |
|
|
### Description |
|
|
Training configurations from the 'random' split of Chig-AIMD. This dataset covers the conformational space of chignolin with DFT-level precision. We sequentially applied replica exchange molecular dynamics (REMD), conventional MD, and ab initio MD (AIMD) simulations on a 10 amino acid protein, Chignolin, and finally collected 2 million biomolecule structures with quantum level energy and force records. |

# 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). |
