Assignment 1: Taverna Workflow

Taverna Workflow

1. Download Taverna program and open Taverna Workbench 1.7.2 showed as below.

2. Import the ‘Get nucleotide FASTA’ into a workflow model by right-clicking at Get nucleotide FASTA and selecting Add to model.

3. Creat new workflow input i.e., Accession number and new workflow output i.e., FASTA sequence.

4. Make connection between input (Accession number) and output (FASTA sequence) to ‘Get nucleotide FASTA’ program. The completed workflow as below. Then run workflow by selecting the file menu at the top of the workbench and clicking Run workflow.

The completed workflow and run workflow.

5. Run the workflow by using Accession number NR_002796.

After the process is completed, the result is shown as below.

6. Modify the workflow by addition of ‘Get Protein FASTA’ program. The step is the same as described above.
Import ‘Get Protein FASTA’, output:FASTA protein sequence and make connection.

Run the workflow by using Accession number AAA57138, AAA57137, NR_002796, NC_007198. The result is shown as below.

7. Modify the workflow again by addition of ‘ClustalWMultiFasta’ program. The step is the same as described above. Import ClustalWMultiFasta’, output:result and make connection.

Run the workflow by using Accession number AAA57138, AAA57137, NR_002796, NW_002501049. The result is shown as below.

8. The final step is saving workflow by selecting the file menu at the top of the workbench and clicking save workflow.
