PS Poly: A chain tracing algorithm to determine persistence length and categorize complex polymers by shape
Fig 10
Persistence length calculations appear stable in the face of noise.
(A) Image sequence showing the addition of noise. The second-row images are detailed views of the region indicated in upper images (red rectangles). The added noise levels for each plot are indicated and range between 0 and 0.03 (std). Calculations of persistence length using different methods: (B) end-to-end distance and (C) tangent-tangent correlation. As before, only data within 10–30 nm contour windows were included in the fits. The expected range for new observations are indicated by the 95% prediction bands.
