Distribution of ORF function categories in the clusters. Chodata set was clustered using IGKA algorithm. We identified the gene distribution of different functional categories into different clusters. The function categories were divided according to MIPS (Mewes et al., 2000). The total number of ORFs in each function category was indicated in parentheses. The cluster number to which the genes were grouped is denoted as "Cluster" column. The ORF number in each cluster is denoted as "Total". The ORF number within each functional category is denoted as "Function ORFs". The percentage of the ORF number within functional category of each cluster in the total ORF number of each cluster is denoted as "Percentage (%)".
