Dataset Name

OMat24 train aimd from PBE 3000 nvt

Description

The aimd-from-PBE-3000-nvt training split of OMat24 (Open Materials 2024). OMat24 is a large-scale open dataset of density functional theory (DFT) calculations. The dataset is available in sub-datasets and subsampled sub-datasets based on the structure generation strategy used. There are two main splits in OMat24: train and validation, each divided into the aforementioned subsampling and sub-datasets.

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). <br>
