I am new in gatk tools, I would like to use GenomicsDBImport to merge GVCFs from multiple samples with whole genome. -L interval is a required option for GenomicsDBImport. For example, -L chr20 for contig chr20. -L chr20:1-100 for contig chr20, positions 1-100.

However, I would like to import whole genome (chr1-chr22) to the database. I tired chr1,chr2, it showed error as follows:

A USER ERROR has occurred: Badly formed genome unclippedLoc: Query interval "chr1,chr2" is not valid for this input.

I want to know any ways to import all the chr into a database by GenomicsDBImport.
