Computational Models of SNPs and Disease Associations

HAPCOMPASS: A fast algorithm for accurate haplotype assembly
  • Given a set of aligned sequence reads in a SAM file and a set of variant calls in VCF format, HAPCOMPASS will assemble reads into haplotypes
Tractatus: an exact and subquadratic algorithm for inferring identity-by-descent multi-shared haplotype tracts
  • Given a set of haplotypes or genotypes, Tractatus will compute a set of identical-by-descent multi-shared haplotypes or runs of homozygosity
DELISHUS: An algorithm for detecting deletions in shared haplotypes using SNPs
  • An algorithmic framework for finding inherited and de novo deletions in a GWAS SNP dataset consisting of trios or pairs
Long-range Trio-Phaser
  • A long-range haplotype phasing tool developed for GWAS SNP datasets consisting of trios
Imperfect Ancestral Recombination Graph (iARG)
  • A collection of tools to reconstruct evolutionary histories which include recombination and back/recurrent mutation events
