    Nanoarray sequenzing, cluster-plot



    I don't understand picture B, it`s an Cluster plot of normalized intensities from a high-density test array with 700nm center-to-center spot distance. This array has 3,4 fold more DNA spots per image than 1,29 micorn arrays. It uses only 4,2 pixels per spot and generates similar raw base discordances.

    Thanks for your help

    B looks like an old satay plot from SOLiD sequencing days. They were used to measure signal strength, purity, and phasing. Dots on each axis line are pure colors with no mixed clusters. Dots furthest from the origin on each axis are higher signal or intensity.

      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...
