are very similar to those of the Jansen model. Again, the coefficient of determination is larger than 0.9 for all four polypeptide models. Also for the 1GPB 3 10 -helix and Trpzip2, the results are rather similar to those of the Jansen model, with slightly larger RMSDs and slightly lower R 2 of 0.86 and 0.54, respectively.
