Figure 4.

Percentages of the total fluctuations captured by principal modes (panel A), and contributions of the principal modes $({\nu }_i^k{\lambda }^k)$ [black $({\nu }_i^k{\lambda }^1)$, red $({\sum }_{k=1}^2{\nu }_i^k{\lambda }^k)$, blue $({\sum }_{k=1}^3{\nu }_i^k{\lambda }^k)$, green $({\sum }_{k=1}^4{\nu }_i^k{\lambda }^k)$, pink $({\sum }_{k=1}^5{\nu }_i^k{\lambda }^k)$, and cyan $({\sum }_{k=1}^6{\nu }_i^k{\lambda }^k)$ lines with filled circles] to the MSFs along the θ (panel B) and γ (panel C) angles for the free monomer aggregation trajectory. The solid black lines on the bottoms of panels B and C correspond to the β-strand regions.
