Number of motif representatives predicted in KEGG pathways.

(a): Total number of motif representatives predicted by SliMFinder in KEGG pathways; (b): number of significantly over-represented motif representatives in pathways with respect to the two reference datasets (hyper-geometric p-value<3e-9, see Materials and Methods); (c): number of significant motif representatives that are novel (hyper-geometric p-value<3e-9, NormIC<0.7). MP: Metabolic pathways; NMP: Non-Metabolic Pathways.
