Time-series of Drosophila head microarray gene expression profiles. Hierarchical clustering of 0 hr, 12 hrs, 2^nd day and 7^th day expression profiles. City Block similarity metric and average linkage methods were used for clustering of arrays. Each time point represents mean of normalized log₂ ratio (635/534) of four biological replicates with balanced dye-swaps. The cluster was generated using Acuity 4.0.
