Correlation between the platforms
Correlation between the platforms was calculated for the log2 intensity signals of genes with probes on all three platforms. Only those genes were compared that were given a present call by the Affymetrix MAS 5.0 software in at least four of the eight hybridizations and scored above background for at least seven out of the 14 hybridizations on CATMA arrays.

| Agilent/Affymetrix RMA | 0.7157 |
| Agilent/Affymetrix MAS 5.0 | 0.7292 |
| Affymetrix MAS 5.0/Affymetrix RMA | 0.9728 |
