Hi Avinash,

Quote:
In both of the runs, if I compare the results with the actual known transcripts from Ensembl, it seems like I am missing many known junctions.
For any one tissue type, a certain (possibly substantial) fraction of the known junctions will not be present simply due to tissue-specific expression of different isoforms. As such, I wouldn't worry about this part of your question.

Also, given the Genomic coordinates of a splice junction, is there a way I can extract, from the Tophat output, the no of IUM (Initially Unmapped reads) that Tophat mapped to span that particular junction?
I doubt this is possible, unless you are MUCH better than hacking into the code and the tmp files than I am.

Best of luck,

Shurjo
