Figure 5

Expression Ratios for 1,648 Genes in MPSS, Affymetrix and Agilent. In this matrix type contour plot, the x- and y-axes are ratios of corresponding pairs in MPSS, Affymetrix and Agilent respectively. The axes are on a log-scale. Contours of expression data are shown on the bottom left frames, with red lines representing the total least-square values. Smoothed histograms of the expression data are shown in the diagonal frames. In the top right frames, R is the Spearman's rank correlation value and S is the slope value for the total least square. All data was log-processed. Genes used are the same as those for Figure 2. Codes for samples are described in Table 1.
