Precision of persistence length measurements by Easyworm. Persistence length P (of W sample, see Additional file1: Table S1) is displayed as a function of the number of chains used to perform the analysis (black symbols). The coefficient of determination CD associated with each fit realized is indicated in colored open symbols and reveals how well the data fit the model. The contour length of the chains analyzed here is ~1.0 ± 0.5 μm (mean ± SD). All data points and their associated error bars are the result of 10 bootstrapping operations (see main text for details). Refer to main text for the meaning of cos θ, R, and δ.
