a Representative examples of invader (INV, blue) and non-invader (NINV, red) parasite tracks showing continuous segments of state 2 (St2) high-motility (HM, lines) and state 1 (St1) low-motility (LM, circles). Scale bar, 40 µm. b HM and LM state alternation over time for two INV and two NINV exemplary trajectories. c–f The best power-law (PL) and exponential (EXP) fits for c INV parasites in the St2 mode, d INV parasites combining the St1 and St2 modes, e NINV parasites in the St2 mode, and f NINV parasites combining the St1 and St2 modes. The insets in (d) and (f) show the fits for St1 mode alone, while insets in (c) and (e) display log-normal plots of the St2 mode, helping to highlight the long-tail distribution of the experimental data. Circles (INV: blue, NINV: red) show empirical data; dashed (black) and dotted-dashed (cyan) lines, respectively, represent the best PL and EXP fits. The adjusted parameters μ and ℓmin, as well as the total number of steps analyzed, are indicated on each graph. Akaike Information Criterion (AIC) values and weight indicate the best fit highlighted using bold italic letters for each dataset. In the insets in (d) and (f), numerical values correspond to (µ; ℓmin; AIC value, AIC weight). c–f Pooled data from seven independent experiments, yielding 27 INV tracks and 161 NINV tracks.
