Figure 1From: Cluster analysis for DNA methylation profiles having a detection thresholdDistribution of methylation values for 91 genes in 48 samples. A histogram of methylation values (PMR) is shown. PMR values were transformed using the natural log. Zeros were assigned a value of -5.5, a value slightly below the lowest log-transformed value. The x-axis shows the methylation value. The y-axis shows the percentage of values in that range.Back to article page
