Hi Jeremy, Thank you for the information.
In addition to reducing the "the Minimum length of reas segments", do I also need to reduce "Anchor length" to get more mapping on splicing junctins? Looks like the setting for "Anchor length" only affects the number of mapped splicing junctions reported in the .splicing junctions output. Is my understanding correct? Does the "regions" mean the number of mapped splicing junctions? Thanks.

I have RNA-seq datasets of several cell types and want to compare the alternative splicing events between cell types. The reads are 36nt in length. Are these reads long enough to map on the splicing jucntions accurately when I run Tophat with stringent parameters (no mismatch)? Thanks.
