Sample correlation using RMA-normalized gene-level signals. (a) Within the Human Exon 1.0 ST array; (b) within the Human Gene 1.0 ST;(c) cross-platform sample correlation of the Exon and Gene ST arrays for 16,482 matched genes.

(c) A cross-platform comparison of samples. For each paired samples (from the Exon array and the Gene ST array, resp.), the sample correlation was calculated using Pearson’s Correlation for 16,482 genes found on two platforms. The number in each box represents the correlation coefficient. The Exon array data is on x-axis, and Gene ST array data is on y-axis
