    The meaning of operation 'B' of CIGAR in SAM format

    There is an operation 'B' (BAM_CBACK) of CIGAR in the source code of samtools(v0.1.19).
    But there isn't any comment about this operation.
    Does someone know the meaning of it?

    Thanks!
    Yan

      It was never really used, but was a proposed operator useful mostly for data from Complete Genomics. There's an email thread from the samtools list about this operator here.

              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              ...
