The file ' ChEMBL32_CTI_literature_only_targets_w_more_than_one_tclass.csv' contains all target IDs for which there is more than one level 1 or level 2 target class assignment. The target classes for these targets could be reassigned by hand if one target class per target class level was desirable for the applications of future users. This has not been done for the provided dataset to ensure reproducibility and consistency between different ChEMBL versions.
