Hi everybody,
I'm analyzing RNAseq data (from Solid, single end, 35nt, srek kit) to discover DE genes. Before starting the DE analysis I always separate reads aligning to the + strand from reads aligning to the - strand. Then I count the number of reads matching all exons. Although Solid sequencing claims to be strand specific I often find reads aligning to the opposite strand within exons. It is far to much for anti-sense transcription. Does anybody have comparable experiences and or an explanation? Thanks in advance.
