  • Bowtie2 Issue:Backward call to driver()

    Hello everyone I'm trying to use bowtie2-build and keep getting backward call to driver for mirror index issue.

    I'm not sure what the issue is

    I'm using

    bowtie2-build -f genome.fa mouse_build

    on the Mus_musculus build from Igenome

    1. Can you post the exact error message?
    2. You can probably find prebuilt indices on iGenomes.

      @milestailsprowe: If you downloaded the tar bundle from iGenomes it already has pre-built indexes for multiple aligners (e.g. look in directories /path_to/Sequence/Bowtie2Index or Sequence/BowtieIndex (for bowtie v.1)).

        I retried bowtie2-build on a set I've gotten it to work and gor Total time for backward call to driver() for mirror index:1:31:06

        All I did was

        bowtie2-build (name of the index) and then (what I wanted it ot be called)

        This is a whole new issue for me

          bowtie2-build is used to "create" new indexes from a plain fasta sequence file. Why are you trying to run bowtie2-build on a pre-built index that is ready for use with tophat/bowtie2?

            I got it to work doing that with Bowtie2-Align before it would say Bowtie2 exited at value 1. I got the Mouse one to to work from Igenome but now a set I've done Bowtie2-Build on before is giving me this issue with the same commands.

              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...
