    SplitNCigarReads exception

    Hi all,

    I'm trying to use the GATK pipeline for analyzing RNA-seq data and to detect variants. According to the GATK Best Practices, I need to allow reads for N cigars.
    So I tried
    java -jar GenomeAnalysisTK.jar -T SplitNCigarReads -R /human_g1k_v37.fasta -I Sample.dedupped.bam -o split.bam -U ALLOW_N_CIGAR_READS

    I started working with version 3.2.2. This works fine for a while, until it comes to a certain line in the BAM-file and spits out this error:
    Bad input: Cannot split this read (might be an empty section between Ns, for example 1N1D1N): 77M54369N2D79N24M

    I looked around on the internet and found that it helps sometimes to add -fixNDN to the command. But this results in the following error:
    Message: Code exception.

    Futhermore, it could be a bug, so I installed the latest version of GATK (3.3.0) but I get the exact same errors (both with and without -fixNDN).

    Any suggestions are most welcomed!
    Thanks,
    Lien

    Hi,

    I think I run into this issue the other day, too. Try the latest nightly build of GATK. That fixed it for me. This is a bug that has been fixed if I recall it right.

    Cheers

      Indeed, the latest build fixed it.

        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
