Table 7 Number of tree searches for each approach needed given different numbers of taxa and partitions.

For BS based calculations it is assumed that only the nodes of the best tree are analyzed and no additional ones. For PABA the number of bootstrap replicates was kept constant with 100. NDI = only NDI is determined; NDI/PABSA = NDI and all lower orders of additions are also determined, a full-blown PABSA approach.
