Fig. 7

A simple self-propelled particle model reproducing the scattered colony pattern. The organization of the panels in this figure (simulations) is the same as that of Fig. 2 (experimental data). a. Simulation of scattered (discrete) colony pattern formation. For details, see Movie S. b. Trajectory of wandering agents over 2000 steps from time 0 of Movie S15. Colors represent the passing count (log) (1 count, cyan; 337 counts, magenta). c. A kymograph of agents on yellow lines in panel a over 2000 steps (top, step 1; bottom, step 2000). d. Colony size distribution of the model at steps 1000 and 2000 of Movie S15. e. Cumulative distribution function of the aggregation size of the model at steps 1000 and 2000
