XIBD: software for inferring pairwise identity by descent

Features

  • Estimates relatedness parameters for autosomes and the X chromosome
  • Computes identity coefficients for autosomes and the X chromosome
  • Detects genomic regions that are identical by descent (IBD) for autosomes and the X chromosome
  • Allows the user to select one of two models to infer IBD
  • Plots IBD segments for simple interpretation of results

How to install XIBD

XIBD is currently available to install as a development version from Github:

# install using devtools packages
devtools::install_github("bahlolab/XIBD")

The HapMap reference data is available from the XIBD web page.

How to use XIBD

See the introduction vignette for details.
