From: Comparative analysis of the transcriptomes of EDL, psoas, and soleus muscles from mice
Differentially expressed genes show five distinct clusters among EDL, psoas, and soleus. a Z-score based hierarchal clustering of the gene subsets identified by k-means clustering of the differentially expressed genes (padj< 0.01 and fold change > 2). The optimal number of k-means clusters was determined using (b) elbow, and (c) gap statistic methods. The color intensities correspond to the average gene expression standard deviation from the mean (cluster centers). Red represents upregulation, and blue represents downregulation
