Under the "Generators" menu item, the users find a list of individual generators implemented in the GenUI framework (Figure ). Currently, only the DrugEx generator is available, but other generators can be added easily by extending the Python backend and customizing the existing React components. In fact, the GUI for DrugEx is based on the same React components as the "QSAR Models" view. Like QSAR models, DrugEx networks can also be serialized and saved as files. For example, a cheminformatics researcher can build a DrugEx model outside of the GenUI ecosystem (i.e. using a script published with the original paper ) and provide the created model files to another researcher who can import and use the model from the GenUI web-based GUI.
