Normalized elutriation expression in the subspace associated with the cell cycle. (a) Array correlation with |α₁〉_N along the y-axis vs. that with |α₂〉_N along the x-axis, color-coded according to the classification of the arrays into the five cell cycle stages, M/G₁ (yellow), G₁ (green), S (blue), S/G₂ (red), and G₂/M (orange). The dashed unit and half-unit circles outline 100% and 25% of overall normalized array expression in the |α₁〉_N and |α₂〉_N subspace. (b) Correlation of each gene with |γ₁〉_N vs. that with |γ₂〉_N, for 784 cell cycle regulated genes, color-coded according to the classification by Spellman et al. (3).
