Effect of imposing minimal gene expression levels on cluster correlation

	No Adjustment	1.9-fold, at least 5% time points	1.8-fold, at least 10% time points	1.7-fold, at least 10% time points	1.6-fold, at least 20% time points
Number of Genes	5657	4317	4045	4346	4280
Optimal Clusters	224	135	118	123	140
Ave. Correlation	0.666	0.706	0.728	0.735	0.719
Max. Correlation	0.925	0.925	0.940	0.947	0.934
Min. Correlation	0.387	0.445	0.478	0.474	0.469

We compare the effects on genes retention and correlation results of within-cluster elements after clustering dataset II by the iterative algorithm.
