  • Maq error:[seq_read_fastq] Inconsistent sequence name

    Hi,
    I've been dowloaded some Illumina/Solexa short read files from SRA such as this one:

    @CCFFFFEFHHGHJJJJJGIIEHGIIJJGIIEGIEBGIJEEFFFFCFFFCDEDDDDDDDDDDDDDDDDBA@CDEEDCDCDDDDCCDCDBDDDDDDCCCDC
    @SRR350739.3 SOLEXA4_0073:2:1101:1220:2247 length=100
    CGAGATATTCAAGATTTCTCTGCTGCTTGTCAGTTGAGAGCGTTGCGATTGGATTCCCGTTCCTCCCCTTGGCTTCGGCTCAGTTCGTCCTTTAACATCA

    CCCFFFFFHHHHHJJJJJJJJIJJJJJJIJJJJIFHHFFDDDDDDDDDDDBDDDDDDDDDEDDBDDDDDDDDDDDDDDDBBDDDDDDDDDDDDDDDDDDD

    and while trying to use the file in maq with the easy run command:

    maq.pl easyrun -d outdir ref.fasta reads.fastq

    I get this error :

    [seq_read_fastq] Inconsistent sequence name: CA>ACDADDDDCCB(<AC@@BBD-<99<?CD. Continue anyway.
    [seq_read_fastq] Inconsistent sequence name: BDBDBDDCDDA9A?<BCCCC>B. Continue anyway.
    [seq_read_fastq] Inconsistent sequence name: 5ACDDDDDCDDDDD. Continue anyway.
    [seq_read_fastq] Inconsistent sequence name: BDCABDDDDDDDDDBDCCCBDDBDBA<. Continue anyway.
    [seq_read_fastq] Inconsistent sequence name: CDC. Continue anyway

    A quick search around reveals that probably this error is due to spaces in the sequence name. Normally I'd remove the spaces in vim editor but these are huge files which can't even open in vim editor.

    Does anyone know an easy way to remove spaces in the sequence name or if I have a different problem other than spaces in sequence name?

    Thanks in advance.

    It looks like a different problem - those are not sequence names it is showing, but bits of quality strings.

      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...
