Reconstruction of proteins from contact maps with random errors. The average RMSD (Avg RMSD) value of the native structure to the corresponding ones reconstructed from blurred contact maps is shown as a function of protein length (Protein length), and at increasing percentage of added random errors (Err %, from 0 up to 15%). The number of errors relative to the same percentage increases with protein size: e.g. 10% of random errors for a protein with length 100 (residues) corresponds to 450 errors; 1% of random errors for a protein with length 400 corresponds to 798 errors. 90,000 contact maps are analyzed.
