Varlociraptor implements a novel, unified fully uncertainty-aware approach to genomic variant calling in arbitrary scenarios.

Key features

  • Calls SNVs, MNVs, indels, inversions, duplications, replacements and breakends in all length ranges (from small to structural) with a unified statistical model.
  • The statistical model encompasses all possible sources of uncertainty and biases.
  • Resulting variant calls can be filtered by false discovery rate. No parameter tuning necessary.
  • Unbiased, maximum a posteriori allele frequency estimates are provided with each call.

Calling modes

  • Generic, grammar based configuration of the statistical model, allowing to classify arbitrary scenarios, from population genetics, to pedigrees, complex tumor scenarios and arbitrary combinations thereof.
  • Tumor-normal-calling, classifying variants as somatic in tumor, somatic in normal, germline, or absent.
