    Bowtie alignment distribution

    hi all,

    I have aligned my RNA-Seq reads to the reference genome using bowtie. Now i want to know where the reads are getting aligned from the map file - like is it coming from repetitive element or exon, etc.
    Please help. Thank you in advance.

    the map file?

      Sorry for incomplete question. I meant from the bowtie output file.

        So the next step would be to use a tool like Cufflinks to quantify expression of genes in terms of some annotation - typically a GTF file from ensemble or UCSC's table browser. That and make a bedGraph of your alignments so you can view them in the UCSC genome browser.

          Thank you.

          Is there any other way we can figure out from the alignment output whether it is coming from an exonic region or repeat region.

          Cheers

            Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.

            I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

            Here are nine questions we think about, in roughly the order they matter, before...
