Evaluation of Microarray Preprocessing Algorithms Based on Concordance with RT-PCR in Clinical Samples
Figure 3
Log-ratio discrepancy between microarray and RT-PCR.
The distribution of the log-ratio discrepancy for each microarray preprocessing algorithm is indicated by a box plot, for a) the colon cancer data set, and b) the cell line data set. Algorithms are displayed in order of the median, such that the more accurate algorithms are at the top. The colorgrams on the right-hand side indicate P values (Wilcoxon test) comparing each pair of algorithms.
