Figure 3.

Quality of model for predicting the hydrodynamic radius. We assessed the quality of the global model (Eq. 7) by back-calculating R_h from R_g and N, and then compared the resulting values to those obtained by HYDROPRO. (A) The results show a strong correlation across the entire range of levels of compactions and chain lengths, with (B) a small increase in error (unsigned error in black) and a bias (signed error in red) toward overestimating R_h for the longest peptides (see also main text). Error bars represent the standard deviation. The differently shaped symbols represent the different datasets: squares for poly-valine, circles for IDP-like, and triangles for IDPs.
