Before revision:  Of the five ND variants tested, the best results at  the macroscopic, mesoscopic and microscopic levels, were produced by a single variant. These ND results extend the utility of protein structure networks to the investigation of partially folded structures, and to the folding process itself .
After revision:  Of the five ND variants tested, the best results at the macroscopic, mesoscopic and microscopic levels, were produced by a single ND variant. Further preliminary exploration of mixed ND variants by chain fold type suggests that these results could be improved with context-sensitive model parameters, and that the ND model could be extended to multi-state folders .
