WGCNA network and module detection. A Selection of the soft-thresholding powers. The left panel displays the scale-free index versus soft-thresholding power. The right panel shows the mean connectivity versus soft-thresholding power. The x-axis represents weighting parameters (power). The y-axis represents the scale-free fit index and connectivity for each power. B Histogram of the number of node connections and validation that the network conforms to a scale-free distribution at a given threshold. C Module division. D Module merge. Each color represents a module in the co-expression network by WGCNA. E Heatmap of the correlation between module and PD samples traits. F The heatmap visualizing the gene network. G Scatterplot showing the correlation between gene significance and module membership in the greenyellow module
