For both force fields used in this study, OPLS3e and CHARMM36, new releases have been published recently. OPLS4 was published in 2021, with updates, e.g., on the representation of hydration and treatment of molecular ions . There were no changes in membrane parametrization. New CHARMM36 parameters called as C36/LJ-PME were also published in 2021 . Parameters have been optimized for lipid membranes with semi-automated approach including long-range dispersion using Lennard-Jones particle-mesh Ewald (LJ-PME) approach . Order parameters were used as one of the optimization targets and based on their study, order parameters for head group and tails of DPPC and DMPC lipids at full hydration align quite well with the experimental data. It will be interesting to see if these new updates offer improved performance for membranes especially in the presence of ions which has been challenging area to be simulated correctly by the earlier force fields.
