[galaxy-user] Iterating over a set of files

Hello, I have a use case where the input to the workflow would be a directory (local to Galaxy instance) with a variable number of files in it. The workflow should iterate over all the files, running the workflow for each one sequentially. How would I got about doing this in galaxy? It's easy enough to write an input tool that takes a directory and outputs the files, but not sure how to make it iterate. Any ideas? ************************************************ Alex Quezada Software Developer Genome Science/Joint Genome Institute (B-6) Bioscience Division MS M888 Los Alamos National Laboratory Los Alamos, NM 87545 phone: (505) 606-2153 fax: (505) 665-3024 email: alexq@lanl.gov ************************************************
