Tox21

My copy of the Tox21 dataset.

Data source

Preparation protocol

All smiles strings (molecules) have been standardised using

https://github.com/flatkinson/standardiser

Molecules that did not pass standardisation have been removed. Cf. standardisation/errors.smi for such molecules.

All molecules tested on a given toxicity endpoint/target were copied into a specific directory for that target. All toxic molecules for a given target have had their name prefixed with the word "active". Each list of molecules was randomized.

Directory structure

tox21.csv: backup copy of the original data source

targets.txt: list of all toxicity endpoints in the dataset; one per line.
             Target names are in the same order than columns
             in the tox21.csv file.

TARGET/ligands_std_rand.smi: all toxic molecules for TARGET and all
                             non toxic molecules; in random order

standardisation/errors.smi: molecules that did not pass standardisation
standardisation/standardised.smi: molecules that passed standardisation
