    ddRAD protocol by Peterson et al.

    Hi,

    Our lab really enjoyed reading Peterson et al. article in PLOS on ddRAD and we have plans to their protocol. I have some question at this stage and I'm wondering if someone please can answer?

    1.Have you ever tried to sequence the ddRAD libraries on MiSeq? We would like to do this but the Norwegian Sequencing Center (http://www.sequencing.uio.no/) informed us that monochromatic motives (ie AATTC entire flow cell because of the EcoR1 digestion) can be difficult to handle for the MiSeq., so if this is the case, there will have to be adjusted slightly in the run parameters, so the failure to detect this motif (AATTC). However, get round this by blending the library with PhIX to 50% (!), and lowering the clustering density to 50% of normal. The result of course is that we only get 25% of the possible output of the MiSeq…
    2. How much PhiX did you load?


    Best,
    Hanne

    Hi Hanne,
    I am curious if you have done any further work with this protocol on the MiSeq and how your results have been?

      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...

      From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
      by SEQadmin2


      Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


      The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
