Sets of microarray features measuring expressed genes (≥ 1 copy per cell) were compared pairwise to calculate the number of members common to each pair. By matching microarray features to the NIA Gene Index, numbers of U-clusters (loci) and transcripts expressed in common were derived for each pairwise comparison. Signal intensities which were lower than those for all spike-in controls, as well as saturated signals, were not converted to copy number estimates (see Materials and methods), so these calculations may underestimate the number of expressed genes.
