    Pindel output Row 32+ per sample details

    Hi,
    I am running Pindel on some Illumina data.
    I am having trouble interpreting the final "per sample" columns of the output files.
    The manual (http://gmt.genome.wustl.edu/pindel/0...er-manual.html) says that lines 32+ are "Per sample" and consist of the sample id, plus 4 values for each sample (ie. the sample name, followed by the total number of supporting reads whose anchors are upstream, the total number of unique supporting reads whose anchors are upstream, the total number of supporting reads whose anchors are downstream, and finally the total number of unique supporting reads whose anchors are downstream.)
    However in my output I get 6 values following every sample name. (eg:
    C9343 5 5 12 10 1 1)
    Can you please explain what these extra 2 values are, and the order of the values.

    Thanks,

    Ruth

      Hi,
      Thanks.
      So to clarify RefSupportingLeft and RefSupportingRight are the number of reads that support the reference sequence, and therefore not the variant?
      Whereas Alt... are the number of reads that support the variant as documented in the rest of the row?

        Ref = reference allele
        Alt = variant allele

        take max(RefSupportingLeft, RefSupportingRight) and sum(AltSupportingLeft, AltSupportingRight) for your genotype. if you run pindel2vcf, this should be take cared already.

          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
