A different population may get absolutely different results using the same setting. In essence, imputation is then performed by identifying the most likely path through the haplotype cluster based on the non-missing genotypes. gz data to match the reference panel. 2 The most recent reference for Beagle’s phasing algorithm is: ing and missing data infer e association studies by use of localized haplotype clustering. The Beagle algorithm uses a modified version of the Li and Stephens haplotype frequency model that reduces the space requirements and a pre-processing step that re-computes an original reference panel into a composite reference haplotypes. 28d.
