Benchmark Data for Chemprop

Datasets and splits of the manuscript "Chemprop: Machine Learning Package for Chemical Property Prediction." Train, validation and test splits are located within each folder, as well as additional data necessary for some of the benchmarks. To train Chemprop models, refer to our code repository to obtain ready-to-use scripts to train machine learning models for each of the systems.
Available benchmarking systems:

`hiv` HIV replication inhibition from MoleculeNet and OGB with scaffold splits
`pcba_random` Biological activities from MoleculeNet with random splits  (with missing targets filled in with zeros as provided by MoleculeNet)
`pcba_random_nans` Biological activities from MoleculeNet with random splits and data format to match OGB (with missing targets not filled in with zeros)
`pcba_scaffold` Biological activities from OGB with scaffold splits
`qm9_multitask` DFT calculated properties from MoleculeNet and OGB, trained as a multi-task model

Version: This version of the dataset (Version 2) is compatible with all versions of Chemprop (supporting the respective functionality). Version 1 of this dataset is compatible with all versions except Chemprop v.1.6.1, which cannot process the `charges_eps_4`  and `charges_eps_78` datasets (all other benchmarks work as expected). We therefore recommend to always use Version 2 of the dataset (with reformatted `charges_eps_4`  and `charges_eps_78`  datasets), since it is compatible with all versions of Chemprop. For use with any other ML software, you can use any version.
