Figure 3
Maximum search-model truncation using four alternative scoring methods. The polyalanine search model was truncated from the carboxyl terminus one residue at a time. Shown is the maximum number of residues that could be removed from the search model before the highest scoring solution obtained in 100 runs of the evolutionary search procedure no longer corresponded to the correct solution. Solutions were scored using the correlation coefficients between observed and calculated structure-factor amplitudes, labelled CC(F), the squares of the structure-factor amplitudes, CC(Fsq), normalized structure-factor amplitudes, CC(E), or the R factor.
