  • 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

        Strategies for Sequencing Challenging Samples
        by seqadmin


        Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
