vcfdist

vcfdist benchmarks variant calls by jointly evaluating phased single-nucleotide polymorphisms (SNPs), small insertions/deletions (INDELs), and structural variants (SVs) across the whole genome.

Key Features:

• Joint variant evaluation: Simultaneously evaluates SNPs, INDELs, and SVs rather than assessing each variant type independently.
• Phasing error correction: Corrects a common flaw in phasing evaluations, reducing measured flip errors by over 50%.
• Improved accuracy: Joint evaluation uniformly reduces measured errors for SNPs (-28.9%), INDELs (-19.3%), and SVs (-52.4%) across datasets.
• Result interpretability: Provides more interpretable benchmarking results compared to previous approaches.

Scientific Applications:

• Variant call benchmarking: Assesses the accuracy of variant calling pipelines for SNPs, INDELs, and SVs.
• Phasing assessment: Evaluates phasing accuracy in genome assemblies and variant call sets with corrected flip error measurement.
• Whole-genome analysis: Supports comprehensive benchmarking across entire genomes rather than limited genomic regions.

Methodology:

vcfdist performs joint evaluation of phased SNPs, INDELs, and SVs for whole-genome analysis, correcting errors in phasing evaluations to improve measured accuracy.
