OverviewCount of read pairs in the F1R2 and F2R1 configurations supporting the reference and alternate alleles
This is an annotation that gathers information about the read pair configuration for the reads supporting each allele. It can be used along with downstream filtering steps to identify and filter out erroneous variants that occur with higher frequency in one read pair orientation.
