Detecting genes defining major trends identified using CIA. The central panel (B) is the CIA from Figure 2. The co-ordinates of the genes in each ordination are shown in the side panels A) Ross cDNA and C) Staunton Affymetrix. The top ten genes at the end of axes F1 and F2 are labelled, where red gene labels indicate genes that were present in both datasets. Genes labelled in bold describe genes that were replicated on the microarray. Genes labelled in blue represent genes that were not contained in the top ten genes, but were in the top thirty genes at the end of each axes and are of biological interest.
