changzhiai/dft_traj
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.
