ToxCast assay endpoint names (aenm) may have changed between the previous release of the CompTox Chemicals Dashboard (released August 2018) and the March 2019 release because updates have been made to the ToxCast assay data source, invitrodb. The ToxCast assay annotation data in invitrodb version 3.1 (, as viewed in the CompTox Chemicals Dashboard, may have been updated, resulting in aenm changes. The numeric assay endpoint identifier (aeid) is intended to remain static between invitrodb releases. To enable easier mapping between aenm in the previous data from invitrodb_v2 ( and the latest release version (invitrodbv3.1), a mapping file is provided for reference.
