I'm performing somatic variant calling with Mutect2. However, besides the *.vcf file, the stats file is not generated.
The Genome Analysis Toolkit (GATK) v126.96.36.199 HTSJDK Version: 2.19.0 Picard Version: 2.19.0
gatk Mutect2 -R hg38.fa -I normal.bam --normal normal -I tumour.bam --tumor tumour -O results/mutect/summary.vcf
Where is my mistake? How can I force to generate stats file?
