Genes in dataset III are clustered by EP_GOS_Clust through a sequential process outlined in Figure 3. Genes in cluster groups A and E are further clustered by the iterative algorithm, yielding an initial and final set of clusters. Precision is defined as the fraction of genes within a cluster assigned to the predominant functional group within that cluster.

^aThe cluster p-value is zero if a GO search did not manage to uncover any significant annotation.

^bAfter iteratively clustering 184 genes into 15 initial clusters ('A' on Figure 3), just one poor cluster remains. The next worse cluster has a -log₁₀(P) value of 4.1.

^cThere are no applicable initial values here since the remaining genes to be clustered are subjected to the second filter before being re-clustered into the initial 6 clusters (see Figure 3).
