Figure 3. Construction of WGCNA co-expression network. (A) Sample clustering dendrogram and the samples whose height > 31 were identified as outliers. (B) Sample clustering dendrogram after cutting the outliers. (C) Soft threshold b = 7 and scale-free topological fit index (R2). (D) Shows the modules with different colors under the clustering tree. (E) Heat map of module-trait correlations. (F) MM vs. GS scatter plot of the purple module. (G) MM vs. GS scatter plot of the cyan module. Red represents positive correlations and blue represents negative correlations.
