- unfolding order for four polymers with $4$, $8$, $12$, and $16$

- average of $400$ data points. The first point in each curve
- represents the average of only the first peak in each of the $400$
- simulated force curves, the second point represents the average of
- only the second peak, and so on. The solid lines are fits of

- $\kappa_\text{WLC}=203$, $207$, $161$, and $157\U{pN/nm}$,
- respectively, for lengths $4$ through $16$. The insets show the
- force distributions of the first, fourth, and eighth peaks, left to
- right, for the polymer with eight protein molecules. The parameters
- used for generating the data were the same as those used for
- \cref{fig:sawsim:sim-sawtooth}, except the polymer length, and the
