Configuration of the data processing workflow. All available data processing tasks currently available are listed (right-hand side). These are dragged-and-dropped into the data analysis workflow (left-hand side). Several of the tasks can be individually configured. Hydra verifies the workflow and notifies the user if problems with the workflow are detected (e.g. missing tasks or nonsense ordering). Saved workflows can be retrieved. A sample workflow is shown in the screenshot and the numbered tasks are referenced in the text.
