Estimated power and adjusted proportions of non-differentially expressed genes for the pilot studies.

Example 1			Example 2
Experiment	Power	π0	Technology	Power	π0
strong, 6 hours	0.27	0.68	Affymetrix	0.32	0.81
intermediate, 6 hours	0.10	0.81	Agilent	0.35	0.65
weak, 6 hours	0.10	0.76	Illumina	0.20	0.84
strong, 5 days	0.60	0.51	Home-Spotted	0.18	0.68
weak, 5 days	0.38	0.73	Solexa/Illumina	0.51	0.52

The power is estimated with a 10% FDR.
