Empty VCF after Strelka

Question

[isMM]

Hello, I am trying to call variants on wgs data using strelka with the following command:

  strelka-2.9.2.centos6_x86_64//bin/configureStrelkaGermlineWorkflow.py \
     --bam groups.bam \
     --referenceFasta hg38/hg38.fa \
     --runDir testStrelka

But after appearing to run successfully, it outputs the "Strelka germline workflow successfully completed" message the vcf file that is returned contains no variants, only the information of the run and the length of the contigs, could this be a problem of my data?

Thanks
