This page contains a summary and description of Q-MAP™ modeling results against the twelve Tox21 data challenge endpoints. It also compares results from competitors (to the extent they are known). All results here have been compiled against the predefined set of test molecules that were used in the Tox21 data challenge. The Tox21 data challenge is the most commonly referenced modeling challenge in predictive toxicology. As such, achieving a good performance against the Tox21 test set is a powerful statement about our platform’s predictive modeling skills.
