Construction of co-expression modules for Staphylococcus aureus by WGCNA. (A) Clustering of samples in GSE33341 to identify outliers. There is no obvious outlier that needed to remove. (B) Determination of soft-thresholding power in WGCNA analysis. The figure showed the scale-free fitting index (left) and average connectivity (right) corresponding to different soft thresholds. And soft thresholding power selected was 7. (C) The cluster Dendrogram of 5000 genes . Each branch represents a gene and the different colors below represent different modules. A total of 11 co-expression modules were constructed. (D) The cluster Dendrogram after merging. When setting the height cutoff value as 0.4, the blue and yellow modules with high correlation are merged. Eventually, there were ten modules in total
