A Fast and Simple Method for Detecting Identity-by-Descent Segments in Large-Scale Data.

American journal of human genetics - 2 Apr 2020

Zhou Ying, Browning Sharon R, Browning Brian L

Abstract excerpt

Segments of identity by descent (IBD) are used in many genetic analyses. We present a method for detecting identical-by-descent haplotype segments in phased genotype data. Our method, called hap-IBD, combines a compressed representation of haplotype data, the positional Burrows-Wheeler transform, and multi-threaded execution to produce very fast analysis times. An attractive feature of hap-IBD is its simplicity:...
