Classification quality for the phenotype member of red or orange cluster. Left: classification of all genomes (266) into genomes that are members and non-members of the 'red/orange' cluster using the nearest neighbor classifier (IB1). Right: classification of oral genomes (15) into genomes that are members and non-members of the 'red/orange' cluster related using the nearest neighbor classifier (IB1). Compared to classification based on all pathways (marked by a horizontal line) and based on randomly picked pathways (red), the classification based on the most relevant pathways yields better separation of the cluster members and other species in both genome datasets.
