I've indexed it with bowtie-build and am trying tophat on it. However, i get a \"Error: Report generation failed with err = 1\". I've poked around for this and it seems to be an I/O error but i have no idea where it could stem from.\r\nFurthermore, the reason i'm even considering the rm version is because of some \"interesting\" tophat behavior. It would seem to get biased towards the repeats and completely miss good non-repeat mapping. I know this sounds very strange, but i have a couple of reads (picked 5 by hand) that it maps nicely if i run them by themselves. However, when they are in a big library with a lot of \"junk-repeats\" it completely misses them.
