For molecule-level features x m , a path to the features can be specified using the keyword --features_path PATH/TO/FEATURES. The provided molecular features are concatenated to the learned molecular embedding prior to the FFN network. The features can be provided as a numpy .npy file or CSV file. For both file formats, the features must be in the same order as and --overwrite_default_bond_features can be used to overwrite the default atom and bond features, respectively. The overwrite option is only available when the additional fea-tures are used as feature. Similar to the molecular-level features, the atom-and bond-level features will be normalized automatically by default. This can be disabled with the options --no_atom_descriptor_scaling and --no_bond_descriptor_scaling.
