1.) Please see attached. 2.) So I did this for tophat and cufflinks. This would be useful for cuffcompare. Cuffdiff uses the gtf files output from cufflinks and not reference gtf files. Following a conversation we had with James, I plan on editing the xml scripts to pull the genome attributes from a previous step as opposed to having to set them.

The diff's are attached. I made it an optional feature. Please let me know if this makes its way into galaxy-central. Ilya, This looks like a good start. A couple questions: (1) Do you have a sample GTF indices file similar to e.g. bowtie_indices.loc.sample ? (2) Would it be useful to provide GTF index files in Cuffcompare, Cuffdiff, and Tophat as well? Thanks, J.
