Dear all

I performed tophat mapping, and generated accepted_hits.bam file. Next, how to calculate RPKM according to this file? Do I have to write a script myself to complete this job? Any suggestions will be appreciated. THANKS in advance.

I guess if you follow the protocol that I showed you on your other post, after doing cuffdiff, it will produce a file diff_out that you can find FPKM in it.

Hi Parham, thanks a lot for your comments! From one PhD thesis, I learned RPKM can be calculated directly after tophat, without cufflinks step, but the author did not describe in details the calculation. Do you have any ideas for his approach? Thanks again.

Hi, no I have no idea. But running Tuxedo won't take much time and by having Nature protocol it is very straight forward.
