Plot of the first two components' loadings against each other. Crosses or gene names represent the variable (hybridization) loadings. Colors indicate the cycle phase to which the hybridizations were classified by Spellman . [23]. M/G1, yellow; G1, green; S, blue; G2, red; M, brown. The labeled arrays are misclassified CDC hybridizations assigned to new cell-cycle phases by PCA.
