Distributions of tree comparisons. Each set of posterior trees is compared to four different single trees: the full and the pruned MCC tree of the main analysis and the full and the pruned MCC tree resulting from the same posterior tree sample. Comparisons are made with bipartition (blue) and quartet (pink) similarity. Abbreviations for datasets are shown in Table 1. Different datasets generally result in similar trees, bipartition returns lower similarities than the quartet metric and pruned MCC trees exhibit higher similarities to the posterior sample than full MCC trees. Note that while the mathematically possible range is the same for both metrics, the expected mean values for the comparison between two random trees are 0.0 for the bipartition metric, and \(\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$3$}\right.\) for the quartet metric [22]. See Additional file 1: Table S4 for rescaled quartet similarities
