Before revision:  We calculated the folding rates (k_F s ) from more than 100 folding trajectories for each value of the solvent viscosity (\eta) at a fixed salt concentration of 200 mM.
After revision:  We calculated the folding rates (k_F ) from more than 100 folding trajectories for each value of the solvent viscosity (\eta) at a fixed salt concentration of 200 mM.
