GenotypeGVCFs: no records in VCF

Dear GATK team,

I am having troubles calling genotypes on *.gvcf produced by HaplotypeCaller in GVCF mode.
When I run GenotypeGVCFs (GATK 3.5), I get only header in resulting VCF file, but no records.
I had no such problem before.

Could you advice on possible reason of the issue and how to fix it?

Here is the command and output:

java -Xmx12g -jar GenomeAnalysisTK.jar \
    -T GenotypeGVCFs \
    -R reference.fa \
    --variant  sample1.g.vcf \
    --variant  sample2.g.vcf \ 
    --variant  sample3.g.vcf \
    --variant  sample4.g.vcf --variant  sample5.g.vcf --variant  sample6.g.vcf --variant  sample7.g.vcf --variant  sample7.g.vcf \
    --num_threads 4 \

note: there are SNPs/INDELs in sample*.g.vcf

Thank you!

    Hi @kirill84,

    Can you try running the command without the --num_threads threading and see if you still get an empty output? Also, be sure to use the latest release for GenotypeGVCFs--either v3.7 or GATK4-BETA to rule out version specific bugs that may have been subsequently fixed.
