[galaxy-user] Using -q trimming options in bwa

Hi everybody, Have any of you updated the python/xml wrappers so that bwa will accept a '-q' argument for quality trimming? It would really be helpful for what we are doing. I've looked and I haven't found a wrapper that does this. Any suggestion on finding something like it or better yet if you have the code could you please share it with me. Thanks! Sincerely, Aung Chi
