Principal coordinates comparing unsimulated (real) samples based on a Jaccard distances, b Bray-Curtis distances, c unweighted UniFrac distances where trees are computed using FastTree, d weighted UniFrac distances where trees are computed using FastTree, e unweighted UniFrac distances where trees are computed using ghost-tree, and f weighted UniFrac distances where trees are computed using ghost-tree. Blue points are simulated and real human saliva samples, and red points are simulated and real restroom surface samples. Plots were made using EMPeror software [26]
