Before revision:  Thermodynamic models that are used for secondary structure prediction report a large number of structures in a limited energy range, often failing in identifying the correct native structure unless complemented by auxiliary experimental data.
After revision:  Thermodynamic models that are used for secondary structure prediction rely on computing the partition function of folding ensembles, and can thus estimate minimum free-energy structures and ensemble populations. These models sometimes fail in identifying native structures in a limited energy range, often failing in identifying the correct native structure unless complemented by auxiliary experimental data.
