Reconstruction of SCOP monodomain proteins from contact maps with random errors. The average RMSD (Avg RMSD) value between the native structure and the corresponding ones reconstructed from contact maps blurred with 5% random errors is plotted as a function of the protein length (Protein length). Results are plotted by distinguishing the different SCOP structural classes, as indicated. Each dot represents the average quality of the reconstructions of a given protein. Only mono-domain proteins of the four major SCOP classes are considered (see section 2.1). For each SCOP structural class, a linear least square fitting curve of the data is computed.
