    Plotting % Occupied by % Pass Filter to optimize loading concentration

    Hi everyone,
    I am working in Ancient DNA laboratory, which has the Next Seq 2000 sequencing platform. I tried to optimize the loading Concentration of different runs by visualizing runs in Sequence Analysis Viewer (SAV) and made a Scatter plot for each one to determine if a run was underloaded, optimally loaded, or overloaded. I would appreciate if anyone could answer me about the following:
    1- If the interpretation of the scatter plots of the next seq 2000 platform is the same as the Nova seq platform ( i.e.Optimal loaded: high pf%, high %occupied, underloaded: positive slope, Overloaded: negative or vertical slope )?
    2- I have three plots that have different shapes that I can not interpret (optimal, underloaded, overloaded) the first one of the Human Affinity enriched library (Ancient DNA library), the second one of force enriched library (Ancient DNA library), and the last one is shotgun ancient DNA library, anyone could help me to interpret?

    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
