  • Error in htseq-count. Large gaps in CIGAR string

    Hi,

    I am getting this error when I run htseq-count (version 0.5.4p3)

    Error occured in line 6684695 of file OUT.gsnap.combined.Control_72_Rep3_R1.fastq.uniq.
    Error: value too large to convert to int
    [Exception type: OverflowError, raised in _HTSeq.pyx:1120]

    The corresponding line in the input file is

    HISEQ:488:C3W46ACXX:4:2111:4082:52860 83 Chr08 6311469 40 28S2M4294966387N45M25S = 63083

    I noticed that there is a very large gap in the CIGAR string. I used GSNAP to generate the alignments.

    Has anyone encountered this before?

    Thanks for your help

    Looks like a bug in gsnap; you should report it. Then remove that read.

      Current Approaches to Protein Sequencing
      by seqadmin


      Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

      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...
