## SIR4 (YDR227W)

A permutation based statistical method (PBM5) ranks this transcript824among allS. cerevisiaegenes based on its periodicity and magnitude of oscillation among five data sets. Using an arbitrary cutoff of 1000, this transcriptis considered periodic. Its weighted average peak occurs at50%of the cell cycle, where we use the M/G1 boundary as 0%. For other landmark peak times see this figure. For further details, please visit our website at http://www.fhcrc.org/science/labs/breeden/cellcycle.

In the first three data sets, data points that have been flagged as suspect are plotted in red.
