  • Tophat2 running test_data Errno 8 failed to Index splices

    Hello,
    I am running into problems when trying to get Tophat2 set up following this tutorial: https://ccb.jhu.edu/software/tophat/tutorial.shtml
    I have Bowtie2, Bowtie2-build, and bowtie2-insect in my path as well as the directory to my tophat2 file.
    When I run the command [tophat2 -r 20 test_ref reads_1.fq reads_2.fq]
    I get the following message:
    [2019-06-04 09:43:21] Beginning TopHat run (v2.1.1)
    -----------------------------------------------
    [2019-06-04 09:43:21] Checking for Bowtie
    Bowtie 2 not found, checking for older version..
    Bowtie version: 1.1.2.0
    [2019-06-04 09:43:21] Checking for Bowtie index files (genome)..
    Found both Bowtie1 and Bowtie2 indexes.

    [Errno 8] Exec format error

    I have seen that others have discovered they have installed the wrong type however I have check and I have installed bowtie2-2.3.3.1-linux-x86_64 and tophat-2.1.1.Linux_x86_64 on my windows system working on a 64 bit PuTTY system.
    Sorry for the drawn out question, I'm fairly new to this and wanted to provide as much info as I could.
    Thanks in advance for anyone who could help

    Genetic Variation in Immunogenetics and Antibody Diversity
    by seqadmin



    The field of immunogenetics explores how genetic variations influence immune responses and susceptibility to disease. In a recent SEQanswers webinar, Oscar Rodriguez, Ph.D., Postdoctoral Researcher at the University of Louisville, and Ruben Martínez Barricarte, Ph.D., Assistant Professor of Medicine at Vanderbilt University, shared recent advancements in immunogenetics. This article discusses their research on genetic variation in antibody loci, antibody production processes,...

    Choosing Between NGS and qPCR
    by seqadmin



    Next-generation sequencing (NGS) and quantitative polymerase chain reaction (qPCR) are essential techniques for investigating the genome, transcriptome, and epigenome. In many cases, choosing the appropriate technique is straightforward, but in others, it can be more challenging to determine the most effective option. A simple distinction is that smaller, more focused projects are typically better suited for qPCR, while larger, more complex datasets benefit from NGS. However,...
