Difference Between Edit-Distance And Mismatch In Tophat
Hi everybody,
I was wondering if any body knows what is the difference between the options in tophat?
-N: number of mismatches and
-read-edit-dist: number of edit distance
what would be the number of mismatches and edit distance respectively for a 2-bp indel?
Thanks, Wen

I have not played with this myself, but from what I understand from http://tophat.cbcb.umd.edu/faq.html#edit_dist
-N/--read-mismatches:
mismatches (i.e. only substitutions, no indels)
--read-edit-dist:
mismatches + indels
Then as per the FAQ entry, you can shift between wanting to exclude indels (--read-gap-length 0) and allowing indels (--read-gap-length > 0 ).
