Most of the resolution is achieved within the first few targets. Minimum spanning sets were generated for strains of Bacillus anthracis, Burkholderia pseudomallei, Escherichia coli, Francisella tularensis, Staphylococcus aureus, and Yersinia pestis. The plot shows how the resolution index (Nstrains− average group size±SD) increases with each additional site.The number of differentiable strains included in the panel design and the size of the minimum spanning set is indicated next to each plot. The dashed vertical lines indicate the number of sites expected in the worst-case (N−1 sites)
