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.
