Figure 2.

An illustration of the progression of end-to-end distances of the ensemble of Ala₃₀ structures along the stretching in and between two characteristic stages. The average end-to-end distance r_ee is shown in red, and the ensemble of trajectories is overlapped in gray. For specificity, the data shown here comes from the pulling of Ala₃₀ for the three stages starting from the initial pull—viz. i = 2 in the notation of the x-axis labels.
