Figure S1. Scatter plots are displayed above the diagonal to illustrate pairwise comparisons between results of different methylation profiling microarray experiments. The corresponding Pearson R² correlation coefficients are shown below the diagonal. This figure includes three replicate arrays each for various tissue samples from each of two donors. Female lung is excluded due to observed genomic copy number deviations. Only cerebellum is included in this set as a representative brain part due to space considerations. The reference tissue in each array is spleen, from the same donor as the test tissue. The red dashed line in each plot indicates the linear regression fit. Cells along the diagonal provide tissue and replicate information. Abbreviation: Cere, Cerebellum. Replicates are indicated by the suffix following the underscore: M1, M2, and M3 are replicates from the male donor; F1, F2, F3 are replicates from the female donor. Most replicate arrays for a given tissue employed different replicates of the spleen reference (see Additional file 1).
