Dataset Viewer

The dataset viewer is not available because its heuristics could not detect any supported data files. You can try uploading some data files, or configuring the data files location manually.

Database (v2)

DFT trajectories cleaned with obvious outlier energy and a force cutoff of 50 eV/Å, grouped by exchange-correlation functional. Each folder contains the individual source datasets plus a merged trajectory of the whole folder (PBE.traj, RPBE.traj, r2SCAN.traj). All files are ASE .traj format.
