Description

Apply a score cutoff to filter variants based on a recalibration table. AplyVQSR performs the second pass in a two-stage process called Variant Quality Score Recalibration (VQSR). Specifically, it applies filtering to the input variants based on the recalibration table produced in the first step by VariantRecalibrator and a target sensitivity value.
