taverna工作流程怎么做？
Design a Taverna Workflow that does:-Receive as input the id of a genomic refseq sequence
-Receive as input a start position in the genomic sequence
-Receive as input a end position in the genomic sequence
-Scans DNA sequences for transcription factors
-Provide as output the report of the scan
-Provide as output the outfile of the scan
-Identify transcription factor binding sites in DNA sequences
-Provide as output the report of the identification
-Provide as output the outfile of the identification
Try to execute the workflow e.g. with the input refseq:NG_000007, 70445, 70545
