Metainference : a Bayesian inference method for heterogeneous systems

Bonomi, Massimiliano ; Camilloni, Carlo ; Cavalli, Andrea ; Vendruscolo, Michele

In: Science advances, 2016, vol. 2, no. 1, p. e1501177

Modeling a complex system is almost invariably a challenging task. The incorporation of experimental observations can be used to improve the quality of a model and thus to obtain better predictions about the behavior of the corresponding system. This approach, however, is affected by a variety of different errors, especially when a system simultaneously populates an ensemble of different...

Molecular dynamics simulations with replica-averaged structural restraints generate structural ensembles according to the maximum entropy principle

Cavalli, Andrea ; Camilloni, Carlo ; Vendruscolo, Michele

In: The journal of chemical physics, 2013, vol. 138, no. 9, p. 094112

In order to characterise the dynamics of proteins, a well-established method is to incorporate experimental parameters as replica-averaged structural restraints into molecular dynamics simulations. Here, we justify this approach in the case of interproton distance information provided by nuclear Overhauser effects by showing that it generates ensembles of conformations according to the maximum...
