    Subsample regions of too high coverage

    Hi all,

    Do you think there is an efficient way of downsampling only a few regions of a bam files (in my case the regions with a too high coverage).

    The idea, would be too randomly remove reads in regions where the coverage is above a given coverage.

    Indeed, in my analyses, those regions cause some steps of the pipeline to become really slow.

    Thanks for all your suggestions...

    OK... I just ran into a great tool that seems to do exactly what I wanted. It is called VariantBam (https://github.com/walaj/VariantBam, https://www.ncbi.nlm.nih.gov/pubmed/27153727).

    ./variant highcoveragebam.bam -m maxcoverage -o reducedmaxcoveragebam.bam -b

    I hope it will be useful for some of you.

        16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
        by SEQadmin2




        NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...

        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
