Extracting gene expression patterns and identifying co-expressed genes from microarray data reveals biologically responsive processes

Table 4 Homogeneity of gene expression profiles within patterns and correlations between patterns

Data	Algorithm	Number of patterns	Overall average homogeneity within patterns	Averaged correlation between patterns
The simulated data	EPIG	5	0.95	0.29
	CLICK	3	0.72	-0.35
	CAST*	8	0.30	-0.08
Dauer recovery and L1 starvation data	EPIG	18	0.83	-0.03
	CLICK	5	0.74	-0.15
UV and IR DNA damage data	EPIG	18	0.84	-0.02
	CLICK	11	0.78	-0.08

* Results generated with an affinity threshold value of 0.8. Two singleton profiles were not reported or included in the analysis of the homogeneity and correlation measures.
