Description

The GATK is a structured software library that makes writing efficient analysis tools using next-generation sequencing data very easy, and second it's a suite of tools for working with human medical resequencing projects such as 1000 Genomes and The Cancer Genome Atlas. These tools include things like a depth of coverage analyzers, a quality score recalibrator, a SNP/indel caller and a local realigner.

We aim to work well with both samtools and Picard by providing complementary tools to those available in those two packages. Our SNP calling pipeline (Q score recalibration -> multiple sequence realignment -> snp/index calling) is a particular area of focus, and have been pushing to make these capabilities as general-purpose and powerful as possible. My group's mandate is to ensure the success of the human medical resequencing projects we've undertaken at the Broad over the next 2-3 years, which involves providing a robust, production-quality development library that underlies tools for common analysis problems (like SNP calling) as well as enabling exploratory research on NGS data.

Additional Information

We provide a wrapper script GenomeAnalysisTK that is equivalent to running

   mkdir -p tmp
   export TMPDIR=$(pwd)/tmp
   java -Djava.io.tmpdir=$TMPDIR -cp /apps/gatk/jexl/2.1.1/commons-jexl-2.1.1.jar -jar $HPC_GATK_DIR/GenomeAnalysisTK.jar

If you do not use the wrapper you must make sure to create and use a local TMPDIR in your /ufrc space with GenomeAnalysisTK.jar. Otherwise /tmp will be used by default leading to filled up /tmp partitions on compute nodes and node failure.
