 OMC25 represents the largest high quality molecular crystal DFT dataset.
-OMC25 was generated at the PBE-D3 level of theory as implemented in Vienna Ab initio Simulation Package (VASP). OMC25 includes structures sampled from relaxation trajectories of molecular crystals generated by [Genarris 3.0](https://chemrxiv.org/engage/chemrxiv/article-details/685d9e933ba0887c33139611) starting from molecules in the [OE62 dataset](https://www.nature.com/articles/s41597-020-0385-y). For more details on the dataset, see [arXiv](https://arxiv.org/abs/xxxx.xxxxx).
