Test-drive the GATK tools and Best Practices pipelines on Terra


Check out this blog post to learn how you can get started with GATK and try out the pipelines in preconfigured workspaces (with a user-friendly interface!) without having to install anything.

java.lang.NullPointerException when running genotypeGVCF on >100 samples

After processing BAM, I made GVCF for each sample, and use genotypeGVCFs here.
Running the following command in parallel mode (multi-threads) cases an error:

/work/share/software/jre1.8.0_111/bin/java -Xmx60g -jar GenomeAnalysisTK.jar -T GenotypeGVCFs -R /work/home/shilab/exomedata/GATK_boundle/hg19/genome.fa --variant input.list -o GenotypeGVCF.beta.vcf -nt 30

The errror is pasted here:
