OPERA is a free and open-source/open-data suite of QSAR models providing predictions on physicochemical properties, environmental fate, ADME and toxcicity endpoints as well as additional information including applicability domain and accuracy assessment. All models were built on curated data and standardized QSAR-ready chemical structures. OPERA is available in command line and user-friendly graphical interface for Windows and Linux operating systems. It can be installed as a standalone desktop application or embedded in a different tool/workflow.
To use the OPERA addin within the OECD QSAR toolbox, the OPERA command line version should be installed. Download the latest release from: https://github.com/NIEHS/OPERA/releases
