# Dataset Name |
|
|
Alexandria geometry optimization paths PBE 1D |
|
|
### Description |
|
|
The Alexandria Materials Database contains theoretical crystal structures in 1D, 2D and 3D discovered by machine learning approaches using DFT with PBE, PBEsol and SCAN methods. This dataset represents the geometry optimization paths for 1D crystal structures from Alexandria calculated using PBE methods. |

# 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). |
|
