From the CG-MD simulations, we computed the transition matrices for the BTA systems in the same way as we proceeded for the M ones. From Figures between the assemblies. Comparing the M system with ε = 40 kJ mol -1 and the BTA system at T = 340 K, we observe that the transition matrices look qualitatively similar. Peculiar, yet relevant differences can be nonetheless noticed. In particular, the free disassembled monomers at the equilibrium are more persistent in time in the BTA system with respect to the M system. Observing free monomers in solution is relatively more likely in the BTA than in the M systems (Figure , 5a,b).
