Figure 2From: Reference-free SNP calling: improved accuracy by preventing incorrect calls from repetitive genomic regionsObserved distribution of cluster depth (black) and the fitted mixed Poisson model (purple) at different sequencing depths (10x, 20x, 30x and 40x) for the simulation datasets of Arabidopsis thaliana. The mixed Poisson model well fits the observed distribution especially at higher sequencing coverages. The depth threshold for genotyping is indicated by a dashed line.Back to article page
