Hello everyone! I am pretty new to GATK. And now I face the following problem: I got g.vcf files for my samples produced by HaplotypeCaller and then I want to consolidate GVCFs using GenomicsDBImport which requires interval list and then proceed to GenotypeGVCFs in order to make joint VCF. How can I make the interval list? My object is rapeseed (Brassica oleracea). Many thanks in advance.
