Screen shots illustrating use of the Conditional Toxicity Value (CTV) Predictor web portal (http://toxvalue.org). Steps include searching for a chemical, verifying its identity, selecting toxicity values of interest, running quantitative structure–activity relationship (QSAR) models, and exporting predictions to a comma-separated-values file.
