Hi everybody,
I'm performing downstream pair-end analysis on Genome Analyzer II data. The reads was aligned against a reference genome using BWA that gives a BAM output. I'm a novice and I have to understand some basic topic in order to build my pipeline.
For example in the flag field I found 0x0010 (strand of the query) and 0x0020 (strand of the mate); what exactly mean they? I mean, the reads are both given in the forward strand or not? To extract the two sequences readed by GAII, have I to do some transformation (i.e. sense to antisense)??
Thanks!
