Comparison between nomenclature-based (NBG) and algorithm-based (ABG) groupings. The reduced phylogeny (left panel) is based on the minimal number of samples needed to capture the diversity based on combinations of all grouping designations. The total number of samples (N = 660) belonging to each grouping is indicated with bar plots and numbers (right panel). Colors are used to visually distinguish groups within a grouping approach (vertically), meaning that each group is assigned a unique color. To illustrate the correspondence in grouping patterns between different grouping approaches (horizontally), similar colors and their gradients are used. See Table S3 for the results of NBGs and ABGs and their group names, which are here shown as different colors. Used abbreviations and the number of distinct groups produced by the grouping: SC—single-character grouping [9 groups]; SCL—single character and L with one digit grouping [14 groups]; rhb—rhierBAPS (level 1 [2 groups], level 2 [7 groups], and level 3 [16 groups]); tc—TreeCluster (threshold 0.006 [5 groups], threshold 0.005 [8 groups], threshold 0.004 [18 groups], and threshold 0.003 [29 groups])
