  • GATK - PrintReads

    Hi all,
    I am trying to use the GATK PrintReads function following the BaseQualityRecalibrator using the following command:

    Code:
    java -jar GenomeAnalysisTK.jar -T PrintReads -R Homo_sapiens.fa -I WGS.sorted.IndelRealigned.fixedbam -BQSR recal_data.grp -o output.file.bam -nct 32
    The sample is a whole genome ~35X coverage. After starting, it tells me that it will take about 40 hours to complete, is that a correct estimate?
    Then after about 12 hours in, the program crashes with an error that says: "There is no space left on the device, so writing failed". We do have plenty of free space available, so I am not really sure what the problem is. Would anyone have any advice for me on this

    My general advice about GATK issues is to try the GATK forum which I have found to be most useful in diagnosing and solving errors.

    Specifically this might be an issue with allocating memory, try using the -Xmx[n] for n space allocated to the process?

      PrintReads uses many, many intermediate files. You're likely filling up your temp directory with intermediate files, so redirect the temp files to a location with more space.

        Hey Ire1234,

        May be that will be using the space of tmp directory while running this command.

        first create a mimic tmp directory in the hard disk and
        try to include java -Djava.io.tmpdir=/data/tmp/ -jar

        command. That works.

          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...
