Figure 4: The merging process of combining GI genes into GIs. Each bar represents a gene in the genome, with the bar height representing the probability of being a GI-gene, calculated from our bagging model. The GIs are basically the genomic regions with a cluster of adjacent GI genes as shown in G1, G3 and G4. Some adjacent GI gene clusters can be extended to become a single GI, as shown in G2.
