Distribution of probe set scores. Probe set score distributions are displayed for four Affymetrix human gene expression microarray platforms: a) Specificity score, b) Coverage score, c) Robustness score, and d) Overall score. Each platform features a different number of probe sets; therefore the X-axis is plotted as a quantile to enable comparison.
