Dear all, My tool does accept multiple input-files, but there are normally bunches of them, so the "repeat"-syntax doesn't appear to be a good idea. Inspired from the workflow-engine-capability to accept multiple input files I wanted to do the same for my tool: <param name="inputSeqFiles" type="data" format="fasta" multiple="true" ... /> Problem: The above "param"-syntax causes Galaxy to caugh up an error message, as soon as I indeed select multiple files. Selecting single files works well. The, to actually access the list of selected files, I would expect the same syntax as for the "repeat"-tag case to work. What I am currently trying from within a <configfile>-section is something like this: #for $inputSeqFile in $inputSeqFiles ...do something with $inputSeqFile #end for Problem: Cheetah complains about $inputSeqFiles not being iterable. Any suggestions or ideas/alternatives to this setting? Thanks in advance and best regards, Uwe
