Yes - let’s say you have hard coded paths… you could put those into a select list pretty easily (just have the paths embedded like the bowtie wrapper does the paired-end vs. single-end select list). You might also want to consider a table lookup though. The bowtie wrapper does that for reference genomes. You can make your own lookup table to refer to whatever files you want, which would allow you to update paths without installing new version of the tool. brad — Brad Langhorst, Ph.D. Development Scientist New England Biolabs On Aug 26, 2016, at 1:06 PM, Katherine Beaulieu <katherine.beaulieu...@gmail.com<mailto:katherine.beaulieu...@gmail.com>> wrote: Hi Brad, So with multiple selection dropdown lists this is possible? Do you have an example of a tool that can do this? Would it be possible to see an example of the tools you are talking about? Thanks for the help!

If there is a selection of these maybe consider turining them into dropdown lists. Either way, these would be no different than e.g. user specified downsampling amounts. or library names, etc. I have tools that accept many of these.

Thanks for pointing me to the Bowtie wrappers as an example.
