Cluster analyses of known miRNAs and novel miRNAs. Each line refers to data from one gene. The color bar represents the log₂RPKM and ranges from green to red. Red indicates that the miRNA has a higher expression level in treated sample; green indicates that the miRNA has higher expression in the control sample and gray indicates that the miRNA has no expression in at least one sample; dotted line indicates that all differentially expressed miRNAs are clustered all in one after four rounds of cluster.
