    gsMapper contigs

    Hello All,

    What does the lower case and upper case Letters in the contigs build by gsMapper represent?

    Also, How is HCDiff (high confidence) variations differences determined?

    Thanks
    HA

    Hi Ha,

    The mapper application uses a combo of flow signals info quality scores, and difference type information to determine if a variant is of high quality. The HCDiffs file contains variants that have at least 3 non-duplicate reads relative to the reference or to other reads at that specific location.

    I also found another thread that discusses uppercase and lower case and maybe helpful.

      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
