I was using GATK4 to call somatic mutation using tumor only mode. I found that it's hard to find the "af-only-gnomad.vcf.gz" file for parameter:
because I was using hg19 as the reference and the chromosome style is "chr1,chr2". I just wonder if there is any download link to access the compatible "af-only-gnomad.vcf.gz" for me to use?
