Extended Data Fig. 2. Chromosome 20 switch error locations.
Switch error locations for 50 validation samples when phased as part of 480 k samples across the entire chromosome 20 (x-axis) with SHAPEIT5. A switch between dark and light blue represents a switch error. At the top is shown the Axiom array phasing when using Axiom array genotypes as validation and at the bottom when using the WGS data as validation genotypes. Many of the small segments in the top panel are due to genotyping errors in the duo/trio parents, which involve incorrect duo/trio phasing as validation. When using the WGS as validation, many of these inconsistencies disappear.
