  • need to deinterleave/split all fastq files within a directory

    I've been using this script in the link below for several years when I need to split PE reads into separate R1 and R2 files.

    deinterleave FASTQ files. GitHub Gist: instantly share code, notes, and snippets.


    Does anyone know of a way to do the same thing recursively to a whole folder? I have 200 RNAseq samples that all need to be split.

    Maybe you could loop over each of the interleaved files and run the script? Something like:

    Code:
    for j in *fastq; do deinterleave_fastq.sh $j *options; done
    If you could tell me your directory structure and the command for how you normally run the program, I could be more specific.

    Cheers,

    Matt.

      Code:
      deinterleave_fastq.sh < interleaved.fastq f.fastq r.fastq [compress]
      The directory structure is just a folder of interleaved fastq files *0001reads.fq, *0002reads.fq, etc.

        Hi lac302,

        Well, you could do something like this:

        Code:
        for j in *reads.fq; do deinterleave_fastq.sh < $j $(basename $j .fq).F.fq $(basename $j .fq).R.fq [compress]; done
        It's still a bit tricky to tell without seeing the full file name, or understanding completely how the program works, but I think this should do the job.

        Best,

        Matt.

          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...
