From: caCORRECT2: Improving the accuracy and reliability of microarray data in the presence of artifacts
Effect of quantile normalization or caCORRECT artifact-aware normalization on probe intensity distribution. The top panel shows the distribution of probe intensities of two microarray chips, one of which has been affected by both a high intensity and a low intensity artifact (red), and the other which is of good quality (blue). The middle panel shows the distribution of these chips after quantile normalization. The bottom panel shows the distributions of these chips after caCORRECT artifact-aware quantile normalization.
