BEAGLE

Description

Beagle website  

BEAGLE is a state of the art software package for analysis of large-scale genetic data sets with hundreds of thousands of markers genotyped on thousands of samples. BEAGLE can

• phase genotype data (i.e. infer haplotypes) for unrelated individuals, parent-offspring pairs, and parent-offspring trios.
• infer sporadic missing genotype data.
• impute ungenotyped markers that have been genotyped in a reference panel.
• perform single marker and haplotypic association analysis.
• detect genetic regions that are homozygous-by-descent in an individual or identical-by-descent in pairs of individuals.
