Determination of soft-thresholding power in WGCNA. a Analysis of the scale-free fitting indices for various soft-thresholding powers (β). b Mean connectivity analysis of various soft-thresholding powers. c Histogram of the connection distribution when β = 3. d Checking the scale-free topology when β = 3. According to c, d, k and p(k) were negatively correlated (correlation coefficient is 0.85), indicating that a gene scale-free network can be resumed
