From what I've seen in Galaxy Main and the recent inclusion of e.g., the MACS wrapper, it seems like the things I've listed would be of interest to the galaxy community at large.

Ideally, we'd like to be able to run the entire pipeline, look at the results, possibly change a few parameters in some of the steps (e.g., minimum FDR cutoff) and rerun only what needs to be rerun. Galaxy workflows are easy to create, but don't seem to have the flexibility that we're looking for. Perhaps several workflows tied together would do the job (i.e., have separate workflows for the major parts of the analysis) which we could tie together (possible in galaxy?) into one uber-pipeline.
