Combinations of GO attributes: Shown is a graphical representation of the contingency tables between the clustering result and the GO annotations. Darker color indicates more genes in that cluster with this annotation. Upper plot: The results corresponding to Fig. 2. The highest scoring attributes as determined by the individual mutual information I(C,A
). The attributes are sorted according to their appearance in the GO database. Lower plot: Combined attributes: Shown are the results for the first 5 entries of Table 5. For simplicity, the combinations are given as binary code A = (A0,...,A4), where A0 = cytosolic ribosome, A1 = cytoplasm. A2 = cell cycle. A3 = nucleus and A4 = catalytic activity. Genes not possessing any of the top five attributes listed in Table 5 are omitted.
