Hierarchical clustering of the phenotype profiles of 49 strains for 8 aspects of escape behavior. Dendrograms resulting from hierarchical clustering of the data in Figure 3I at the indicated ΔT are plotted. In the heatmaps, the strains are reordered by the dendrograms. The strains labeled with red font have a probability ≤ 0.1 to be in the same cluster as N2 (depicted with orange color) as determined by 10,000 bootstraps of their behavioral profiles at each ΔT as described in the Methods section. The behavioral features are as follows: MRD, mean reversal duration; MPD, mean pause duration; MAXS, average maximum speed after laser pulse; TMAX, mean time to reach MAXS; ACCN, mean acceleration; FP, forward to pause transition probability; FR, forward to reversal transition probability; FF, forward to forward transition probability.
