Mapping of expression clusters to functional gene classes.

	G1	S	S/G2	G2/M	M/G1
wave1	210	2	2	2	25
wave2	46	63	67	2	1
wave3	0	1	38	125	3
wave4	9	1	2	24	58
wave5	35	4	12	26	42

This table shows the number of genes with different peak time for each cluster in yeast cell cycle data. From the highlighted numbers in the table, we can characterize the modules: It is clear that Module 1 is responsible for genes with peaks in M/G1 or G1, followed by Module 2, and so on.
