Table 10 Number of inferred periodic genes from real microarray data. Results obtained by using real microarray data are presented here. Permutation tests were used to obtain significance values for the robust spectra. Symbols: N is the length of the time series, M is the number of genes analysed, P (resp. P') is the number of found periodic genes having an unknown frequency (resp. frequency corresponding to the cell cycle length). Notes in the table: ^aSince the elutriation time course did not show any significant periodic components, we did not perform the test with a fixed frequency. ^bThe average spectrum showed several major peaks. The one in the vicinity of the assumed cell cycle frequency was chosen manually.
