ibdsim2: Simulation of Chromosomal Regions Shared by Family Members
Simulation of chromosomal segments shared
identical-by-descent (IBD) among pedigree members. Using sex-specific
recombination rates along the human genome (Halldorsson et al. (2019)
<doi:10.1126/science.aau1043>), phased chromosomes are simulated for
all pedigree members. Applications include calculation of realised
relatedness coefficients and IBD segment distributions. 'ibdsim2' is
part of the 'pedsuite' collection of packages for pedigree analysis.
A detailed presentation of the 'pedsuite', including a separate
chapter on 'ibdsim2', is available in the book 'Pedigree analysis in
R' (Vigeland, 2021, ISBN:9780128244302). A 'Shiny' app for visualising
and comparing IBD distributions is available at
<https://magnusdv.shinyapps.io/ibdsim2-shiny/>.
