Figure 11

Plot of means and coefficients of variation of expression data obtained with different probe sets annotated to one gene with Spearman's correlation ρ ≥ 0.9 (upper panel) and 0.7 ≤ ρ < 0.9 (lower panel). Each dot represents means of expression data (left part) or coefficients of correlation (right part) obtained with two probesets corresponding to one gene on the Affymetrix U133A microarray in GSE1133 dataset (probe set 1 on the x-axis and probe set 2 on the y-axis). Black line represents linear regression line and its equation is in the top left corner of plot. See also Additional file 5 Supplementary Fig S4.
