    Cluster metrics for individual barcodes

    Hi all,

    I wonder if it is possible to assess some useful cluster metrics (FWHM or %>=Q30) not for the entire loaded pool but for individual barcodes (or maybe even for separate reads)? The Illumina SAV can show such stats for particular lanes/tiles but does not track the barcodes. In principle, each read can be tracked back to its location in the flow cell by coordinates extraced from the read name, but is there a way to relate it to a particular cluster and get its size?

    In the "stats/" directory produced by bcl2fastq you can find an XML file with per-tile metrics on %>=Q30 separated by barcodes.

      Thanks a lot, I completely forgot about it.

        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

        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...
