Curated OpenFF PhAlkEthOH Dataset: Full dataset, version "full_dataset_v1": This provides a curated hdf5 file for the OpenFF PhAlkEthOH dataset designed to be compatible with modelforge, an infrastructure to implement and train NNPs. This dataset contains 1,188,691 total conformers, for 12,271 unique molecules. This excludes conformers where the magnitude of the forces on the atoms are greater than 1 hartree/bohr. When applicable, the units of properties are provided in the datafile, encoded as strings compatible with the openff-units package. For more information about the structure of the data file, please see the following: https://github.com/choderalab/modelforge/wiki/Dataset-and-curation#curation-module This curated dataset was generated using the modelforge software at commit <update after PR merge>: Link to the source code at this commit: <update after PR merge> Link to the script file used to generate the dataset: <update after PR merge> Source Dataset: PhAlkEthOH: Phenyls, Alkanes, Ethers, and alcohols (OH) The PhAlkEthOH dataset contains a collection of optimized geometries of linear and cyclic molecules containing phyl rings, small alkanes, ethers, and alcohols containing only elements carbon, oxygen and hydrogen. For each unique molecule, conformers correspond to snapshots from the optimization trajectory. All QM datapoints retrieved from The MolSSI qcarchive and were generated using B3LYP-D3BJ/DZVP level of theory, the default theory used for force field development by the Open Force Field Initiative.
