Error-rate results of the DCES problem. Implementation of the procedure for the DCES problem on six genomes: E. coliOHE (A.), D. radiodurans (B.), and P. aeruginosa (C.), A. pernix (D.), B. aphidicola (E.) S. cerevisea (F.). For each organism, the graph includes the error rate (red; % of the sites not in the DS were not reconstructed accurately based on the DS) and the % of sites that were reconstructed based on co-evolutionary relations (blue; i.e. their value cannot be inferred based on their evolutionary tree), for different sizes of the dominant set (% from the total number of proteins in the genome, x-axis).
