Platform concordance and factors affecting it for genes represented on both ATH1 and tiling arrays. (a) Pearson correlation coefficients (PCCs) of expression estimates. (b) Box plots showing expression correlation for genes that were either categorized by the number of probes on tiling arrays or categorized by the total length of nonredundant sequence spanned by ATH1 probes. The boxes have lines at the lower quartile, median, and upper quartile values. Whiskers extend to the most extreme value within 1.5 times the interquartile range from the ends of the corresponding box. Box plots are based on genes represented on both the ATH1 and the tiling array, with the total number of genes per category on the respective platform indicated at the top.
