  • bowtie2-align dided with the signal 11 (SEGV) (core dumped) with bowtie2

    I am running bowtie2 to map 300 bp reads to a fixed set of amplicons.

    I always get a "bowtie2-align died with the signal 11 (SEGV) (core dumped)" error regardless of whether I use the ubuntu version of bowtie2 or a self compiled version of bowtie2 ( ver 2.2.5)

    The error is Ubuntu specific as I have tested it with self and ubuntu compiled versions on Ubuntu servers , running both 12.04 and 14.04 on my personal hardware and on Amazon EC2 ( controlling for hardware issues) with both 16 GB and 98 GB of memory ( all 8 combinations gave the error )

    When I switched the same workload to a server running SUSE Linux on Amazon EC2 or ran it on my dev laptop running OS X with 32 and 16 GB of RAM respectively, I never get the "bowtie2-align dided with the signal 11 (SEGV) (core dumped)" error.

    I don't know how to run bowtie2 in debug mode to troubleshoot this error . Any help understanding why this error occurs will be greatly appreciated.

    Essential Discoveries and Tools in Epitranscriptomics
    by seqadmin




    The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...

    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...
