Fig. 7From: Amplitude spectrum distance: measuring the global shape divergence of protein fragmentsCorrelation between ASD and its variants over all fragment pairs of SkF 20 a ASD vs NASD, Pearson correlation coefficient is 0.53. but reaches 0.9 when zooming on values of ASD below 1000 b ASD computed using all the 40×40 Fourier coefficients vs truncated version of ASD computed using only 5×5 first Fourier coefficients, Pearson correlation is 0.95Back to article page
