    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.

          From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
          by SEQadmin2


          Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


          The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.

          Single-Cell Sequencing at an Inflection Point: Early Impacts of New Platforms and Emerging Trends
          by SEQadmin2


          With the launch of new single-cell sequencing platforms in 2026, the field stands at an exciting inflection point. This article surveys the most impactful advances in the field and discusses how they’re reshaping research in cancer, immunology, and beyond.


          Introduction

          Single-cell sequencing technologies have undergone remarkable advances over the past decade, transitioning from low-throughput experimental approaches to highly scalable platforms capable of...

          Environmental Genomics in the Age of NGS: From Microbes to Conservation Strategies
          by SEQadmin2

          Studying ecosystems means dealing with complex, multi-species communities that are hard to observe at scale. This complexity, however, hides many important questions to be answered, from how biogeochemical cycles work and how climate change can affect species distribution to how conservation strategies can work best.


          Genomics, particularly since the expansion of NGS, has transformed ecosystem ecology. By sequencing environmental DNA, we can now assess biodiversity without direct...
