Package: ibdfindr Title: HMM Toolkit for Inferring IBD Segments from SNP Data Version: 0.5.0 Authors@R: person("Magnus Dehli", "Vigeland", , "m.d.vigeland@medisin.uio.no", role = c("aut", "cre"), comment = c(ORCID = "0000-0002-9134-4962")) Description: Implements continuous-time hidden Markov models (HMMs) to infer identity-by-descent (IBD) segments shared by two individuals. Supports two- and three-state models using single-nucleotide polymorphism (SNP) genotypes or genotype likelihoods. Provides posterior probabilities at each marker (forward-backward algorithm), prediction of IBD segments (Viterbi algorithm), and functions for visualising results. Supports both autosomal data and X-chromosomal data. The methodology and package are described in Vigeland et al. (2026) .
