    Problemastic reads quality score distribution by dwgsim

    Hi there,

    I was using dwgsim to do illumina reads simulation for my study. The command I used is like this >>
    dwgsim -e 0.0001-0.01 -E 0.0001-0.01 -d 100 -s 75 -1 100 -2 100 -C 2.5 -r 0 -R 0 -y 0.01 -c 0 -H hap1.fasta sim.hap1.dwgsim

    So I should expect a decreasing quality score from 40 to 20 along the simulated reads on average. But the quality scores I got from the simulated reads revealed a very different picture>>

    What might be the reason for this? Thank you very much!

    Problem solved. The profile attached seems to be generated from older version of the simulation where the error rates were specified as 0.0001-0.1 sorry about that.

      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
