2. Kepler: http://kepler.ecoinformatics.org http://kepler.ecoinformatics.org

3. Kepler  framework for design, execution and deployment of scientific workflows  … based on Ptolemy II

4. Kepler Interface  The graph editor Tool bar Actor library Director library

5. Graph Editor Model building area Library of components Navigation area Tool bar Search

6. Tool Bar Viewing Running model Adding ports

7. Viewing Zoom In Zoom Reset Zoom Fit Zoom Out Full Screen

8. Running Model Run or resume model Pause the model Stop the model

9. Running Model

10. Adding Ports New input port New output port New input/output port New input multiport New output multiport New input/output multiport

11. Adding Ports  There are two ways to add ports One to connect workflows (AKA composite actors) One to connect actors within workflows

12. Adding ports to actors

13. Searching  Data  Actors  Directors

14. Actors  Actors are components that execute and communicate with other actors in a model.

15. Actor Library  Variety of Actors grouped based on the type of functions

16. Director  Governs the execution of a workflow.

17. Configuring the Director

18. Renaming the Director

19. Get documentation

20. Director Library  A variety of directors depending upon the type of model being executed.

21. Using Kepler  Executing a ready to run workflow  Building a model Choosing actors Making connections Choosing a director Building composite actors Saving and running the model
