ratio_heterozygous_homzygous_snv

metrics.ratio_heterozygous_homzygous_snv(mqc, biosample_id)

Description: The ratio of heterozygous and homozygous variant type SNVs in VCF, only in autosomal regions, high quality variants.

Implementation details: In the NPM-sample-QC reference implementation, calculate the ratio of heterozygous and homozygous variant type SNVs in VCF, only in autosomal regions, high quality variants by bcftools view, (bcftools view -H -v snps -f PASS -g het / bcftools view -H -v snps -f PASS -g hom).
