Aardvark

A tool for sniffing out the differences in vari-Ants

Aardvark was built to quickly compare different variant call sets. Key features of Aardvark include:

• Ability to benchmark variants from a "query" set against those from a "truth" set
  • Constructs haplotype sequences, allowing for basepair-level comparisons that are variant-type agnostic and that enable implicit partial credit for inexact matching variant calls
  • Genotype assessment, allowing for a strict exact-match scoring (similar to traditional metrics)
  • Provides output summary statistics and VCF files with annotations
• Ability to merge variants from multiple input sets
  • Variants are compared in a haplotype context (sequence level), harmonizing different variant representations
  • Multiple merge strategies for different scenarios from strict exact-matching to looser majority-vote schemes
• Quality of life additions: Efficient methods with a fast run-time distributed as a single binary
