  1. For all arrays of a given batch, the mean intensity value for each gene was first calculated considering all intensity measurements above 95% of the background threshold. Distribution of intensities were computed for all genes. Results are described by their medians and means. The transcript abundance (TA) is the mean intensity of the probe in the batch over mean intensity of the background signal.
