  • 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.
