Additionally, to maintain consistency, in all cases, we provide the populations for each interaction pattern corresponding to a specific aggregate size (up to tetramers). Then, the relative concentrations of monomers, dimers, trimers, and tetramers are computed from the equilibrium constants for aggregate formation. These constants are determined either from free energies (Q/s method, Eq. 5) or average populations (C/d method, Eq. 9).
