The scaling and repartition of the mass in the water molecules has large effects on the autocorrelation functions of the collective variables. Panels E and F in Figure , and panels D-F in Figures 9 and 10 present the autocorrelation functions of each order parameter and collective variable of the peptide systems. From these plots, it is clear that the decrease in water viscosity due to the mass scaling scheme leads to a faster decorrelation. Furthermore, the integrated autocorrelation times drop by about a factor of two for most systems (Table ). Additionally, the exponential autocorrelation time, τexp was also calculated by linear regression over a reasonably linear regime in log space for the slowest observed process in the autocorrelation function.
