Counts and frequency of alleles in called genotypes (AC, AF, AN)
Category Variant Annotations
Overview
Counts and frequency of alleles in called genotypesThis annotation outputs the following:
- Number of times each ALT allele is represented, in the same order as listed (AC)
- Frequency of each ALT allele, in the same order as listed (AF)
- Total number of alleles in called genotypes (AN)
Example
AC=1;AF=0.500;AN=2
This set of annotations, relating to a heterozygous call(0/1) means there is 1 alternate allele in the genotype. The corresponding allele frequency is 0.5 because there is 1 alternate allele and 1 reference allele in the genotype. The total number of alleles in the genotype should be equivalent to the ploidy of the sample.
