ReporTree running times for the 10 replicates of each subset of L. monocytogenes (top left), S. enterica (top right), E. coli (bottom left), and C. jejuni (bottom right), where the flag all indicates subsets for which ReporTree obtained clusters at all possible thresholds, the flag outbreak indicates subsets for which ReporTree obtained clusters at potential outbreak level (7 allelic differences for L. monocytogenes , 14 (0.43%) for S. enterica , 9 (0.34%) for E. coli , and 6 for (0.59%) for C. jejuni [ 14 , 38 ]), and the flag stability indicates subsets for which ReporTree obtained clusters at all possible thresholds but only generated reports for those corresponding to stability regions.
