    Scaffolding with Newbler?

    Hi,

    We have an existing assembly that we'd like to scaffold using BAC end sequences. Since we've had good experiences with Newbler, we thought we could try to use that. However, Newbler (at least version 2.8) doesn't seem to allow us to open an *existing* (non 454) assembly and combine it with the BES... Also, it doesn't seem to have a way to specify the insert size (and our contigs are much shorter than BACs).

    a) Can Newbler do this kind of job?
    b) Which other scaffolders would you recommend?


    Cheers,

    Newbler is not a stand-alone scaffolder. Also, it cannot be told the insert size. Instead, it determines the library insert distribution based on placement/mapping of the mates in the contigs it builds. So, newbler needs to be able to build contigs from your data that are long enough for a sufficient number of mates to map to the same contig.

    Looks like you need a stand-alone scaffolder...

      Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
      by SEQadmin2



      Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

      Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

      New Genomics Technologies Take Aim at Long-Standing Limits
      by SEQadmin2


      Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

      We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
