Hi Jen Thanks for your reply. Yes, it is my own tool. The outputs element is <outputs> <data format="gff3" name="output"/> </outputs> In the command element, the three output files are defined as below $output /$__new_file_path__/primary_${output.id}_samWithPeptides_visible_sam /$__new_file_path__/primary_${output.id}_longestORFs_visible_fasta Is there anything wrong here? Best regards!

I wouldn't think this is a problem with workflows at first pass. Is this your own tool? Or a tool from the tool shed (the repo developer is usually the one to make changes, unless you want to try)? This is the primary tool development wiki, the " <output> tag set" is where I would double check the tool first. http://wiki.galaxyproject.org/Admin/Tools/ToolConfigSyntax I am moving this over to the galaxy-dev@bx.psu.edu<mailto:galaxy-dev@bx.psu.edu> mailing list since it is a tool development question.

Gff3 will be visualized in IGV and the fasta file is doing further BLAST analysis. Now the problem is that the automatically generated workflow does not connect the having-multiple-output tool and the BLAST tool. I failed even I tried to connect these two tools in the workflow by hand. I am guessing this is due to only the main output type (gff3) is recognized in the workflow. How could I solve this problem? Best regards and have a nice weekend!
