Question: Counting Rna-Seq Reads Per Class.

Hi All, I have been trying to count the number of RNA-seq reads that fall into the various Cufflinks class codes ('=', 'j', 'u', 'x', etc...) and I am curious how others are determining how to count reads per class.. I tried first using the BedTools tool where you "count" the number of reads overlapping another set of intervals and later realized that each interval is extended1 kb up and downstream prior to the analysis (by default and not adjustable on Galaxy), so the number of reads that were "counted" for all of the classes was always much more than the amount of reads that I had for my Bam file. I then tried to isolate reads from each class into separate BAM files, using the BedTools "intersect" tool and there I consistently end up with significantly less reads than I have in my sample. I am very curious to find out how others are tackling this problem on Galaxy. Thanks for any input! Cheers, Mo Heydarian
