  • Abyss-PE error

    Hi community,

    I am currently involved in a rather complex project where we are hunting for causal SNPs in a species that has no assembled genome at the moment. We are planning on sequencing some normal plants to get partial assemblies and then in another run a pool of inbred mutants and hopefully pick up the causal mutant.

    Anywayz, needless to say, the assembly is crucial. So I am using Abyss in an experimental phase to test different settings (>1000 settings to test...). But before I start 1000 assembly jobs, I need to be sure that Abyss is working as desired.

    I just take a genome of a related species, chop it up, get some errors in, pick a coverage, feed it to abyss and check for avg contig size, size distribution, % of original covered etc.

    regular ABYSS is working like a charm.
    abyss-pe is not...

    My fasta file looks like reads_1.fa
    >1A
    ACGACTACGCGA
    >2A
    ACGACTACG

    reads_2.fa
    >1B
    ACGACGA
    >2B
    ACGACTCAG

    The commando I run:
    /data/abyss-1.2.5/bin/abyss-pe k=15 n=40 -o 3334.assembly.fa in='3543.reads_1.fa 3543.reads_2.fa' name=3334

    The error I get:
    ABYSS -k15 -q3 --coverage-hist=coverage.hist -s 3334-bubbles.fa -o 3334-1.fa 3543.reads_1.fa 3543.reads_2.fa
    ABySS 1.2.5
    ABYSS -k15 -q3 --coverage-hist=coverage.hist -s 3334-bubbles.fa -o 3334-1.fa 3543.reads_1.fa 3543.reads_2.fa
    Reading `3543.reads_1.fa'
    ABYSS: FastaReader.cpp:85: bool isColourSpace(const std::string&): Assertion `!seq.empty()' failed.



    What am I doing wrong?

  • #2
    get rid of that
    Code:
    -o 3334.assembly.fa
    part of your command and you should be OK.

      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...
