Taverna Workflow 3. Summary representation of a Workflow that uses ArkDB, DDBJ and GenBank web services to find potential sequence homologies to Sheep Chromosome Y, captured from Taverna Workbench v1.7.0.0. (The actual Workflow is more detailed and uses a temporary file to reduce the number of calls to the external services by removing GenBank sequence ID redundancy, this diagram is available as additional file 7: fig5.pdf, and the Workflow document as additional files 8, 9 and 10: demoWorkFlow3.xml, appendtoFile.xml, listFromFile.xml). The input parameters 'Sheep' and 'Y' are used to retrieve all Maps for this Chromosome from ArkDB, the Map accession numbers are used to retrieve full details of all these Maps including all the Mappings of Markers, and the Marker accession numbers are used to retrieve full details of all the Markers on these Maps. Where these Markers are associated with a sequence, the fasta formatted sequences are retrieved from GenBank and these are used to perform a BlastN search using DDBJ services. All GMD DataSet documents are output for the Map and Marker details, as are the fasta sequences from GenBank and the Sequence similarities found at DDBJ.
