MuTect2 sample names
My MuTect2 VCF records header looks like this:
#CHROM POS ID REF ALT QUAL FILTER INFO FORMAT TUMOR NORMAL
The samples are named TUMOR and NORMAL rather than by the actual names. It doesn't appear like the real sample names are stored anywhere in the VCF file. Is that correct? Is there a way to add sample names to the VCF file?
