Taverna Workbench
The Taverna Workbench allows users to construct complex analysis workflows from components located on both remote and local machines, run these workflows to process data and visualize the results. To support this core functionality it also allows various operations on the components themselves such as discovery and description and the selection of personalized libraries of components previously discovered to be useful to a particular application.
