Fig. 2From: Genome-wide identification of methylated CpG sites in nongenital cutaneous wartsScatter plots showing the coordinates of the wart (W) and normal skin (NS) samples (a) after performing Kruskal’s multi-dimensional scaling based on the matrix of the average methylation levels and Euclidean distance and (b) on the first and second principal components. A clear difference between the W and NS samples can be seen in both plotsBack to article page
