    Annotating mRNA-Seq maps/alignments

    Hey all,

    Bear with me as I ask a noob question, I'm completely overwhelmed by the information on analysis software that's out there and not sure what applies to what I want to do with my data.

    I have a set of mRNA-Seq raw data files (as well as eland analyzed files) from an Illumina 1G GA and I've managed to figure out how to align my reads to a reference genome (using Bowtie, yeilding .map or .sam files). Now what I really want is to get reads per gene, I'm purely interested in gene expression levels, not splice variants or stuff like that.

    What would be the best way to do this? Where would one obtain the annotated reference sequences (the genbank ones on NCBI seem to all be small chunks categorized per chromosome). What software do people use for this? Any help on this is much, much appreciated.

    Cliff notes: have aligned mRNA-Seq data, want reads per gene, how?

    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.

    Nine Things a Sample Prep Scientist Thinks About Before Sequencing
    by SEQadmin2


    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...
