Figure 4.

Model fits by ALStructure, Admixture, fastSTRUCTURE, and terastructure on two particular simulated datasets. The left panel shows the fits corresponding to the dataset on which ALStructure performed the best. The right panel shows the fits corresponding to the dataset on which ALStructure performed the worst. Each point represents a column of the $\mathit{Q}$ matrix and is plotted by the first and second coordinates. Blue points are plotted as a visual aid and delineate a common subset of individuals.
