    Read trimming- color space

    Any ABI-recommended programs for read-trimming? I understand it might not be necessary due to the nature of BioScope's mapping software. Thank you.

    No need for read trimming.

      but you my need to use masks...

        We doubled our mapping by trimming all reads > 35b to 35b

        Please see thread in the Bioinformatics forum.

        best,

          You can look at quality values of the reads. If you see drastic drop down in quality values at the end of every reads , you can trim reads by several bases....which should increase mapping... If you use corona_lite for mapping there is an option of masking several positions during mapping...

          Bioscope mapping is seed based , so even if you dont trim , reads will still map the reference...

            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
