Atomistic fragment simulations were mapped into coarse grained (CG) resolution using MD-Analysis . The bonded terms were then measured and the distributions plotted. The fragment was then modeled in CG and simulated for 1 𝜇s in water with 0.15 mM NaCl. The bonded distributions were fitted onto the corresponding atomistic distributions. For the highly hydrophobic fragment, a bulk simulation was performed as well for 1 𝜇s.
