CIPRes in Kepler: An integrative workflow package for streamlining phylogenetic data analyses Zhijie Guan1, Alex Borchers1, Timothy McPhillips2, Shirley Cohen3, Mark A. Miller1, Ilkay Altintas1 1San biology.sdsc.edu Diego Supercomputer Center, UCSD 2University of California, Davis 3University of Pennsylvania What is a Scientific Workflow? Combination of Mission of scientific workflow systems data integration, analysis, and visualization steps larger, automated "scientific process" Promote “scientific discovery” by providing tools and methods to generate scientific workflows Create an extensible and customizable graphical user interface for scientists from different scientific domains Support computational experiment creation, execution, sharing, reuse and provenance Design frameworks which define efficient ways to connect to the existing data and integrate heterogeneous data from multiple resources Make technology useful through user’s monitor!!! biology.sdsc.edu Promoter Identification Workflow Source: Matt Coleman (LLNL) biology.sdsc.edu A Workflow for Phylogeny Analysis biology.sdsc.edu Kepler is a Scientific Workflow System www.kepler-project.org … and a cross-project collaboration June 2, 2006 Beta release Builds upon the open-source Ptolemy II framework Ptolemy II: A software system used for prototyping engineering system KEPLER: A platform to design and execute Scientific Workflows KEPLER = “Ptolemy II + X” for Scientific Workflows biology.sdsc.edu Some Kepler Contributors Ptolemy II Griddles SKIDL Resurgence SRB NLADR Other contributors: - Chesire (UK Text Mining Center) LOOKING - DART (Great Barrier Reef, Australia) - National Digital Archives + UCSD-TV (US) -… biology.sdsc.edu Contributor names and funding info are at the Kepler website!!
