Analysis of the expression levels and daily rhythmicity of clock genes by COSOPT or R analysis in rat retina and liver.

Amplitude, mean amplitude of the identified time series (theoretically zero); Period, mean period of the identified time series (theoretically 24); Phase, mean time of acrophase of the identified time series (theoretically zero); pMMC-Beta, mean multiple measures corrected significance probability β value. Genes with a period of between 20 and 28 hr with pMMC-β value of Pr values have been calculated by the single cosine R analysis. Genes with Pr value of
