If you need to perform multi-step or repetitive analysis that involves invoking several services, or if you find yourself copying and pasting results between different Web pages or services, and would like to automate this process, then Taverna could be suitable for you.
Taverna allows you to define how your data flows between the services, without having to worry how you are going to invoke these services. It helps you convert data from one format to another in cases when the services you are using are not 100% compatible.
