New in version 0.16.0.
The module contains implementations of similarity measures between protein ensembles described in [ᵃLindorff-Larsen2009]. The implementation and examples are described in [ᵃTiberti2015].
The module includes facilities for handling ensembles and trajectories through
the Universe class, performing clustering or dimensionality reduction
of the ensemble space, estimating multivariate probability distributions from
the input data, and more. ENCORE can be used to compare experimental and
simulation-derived ensembles, as well as estimate the convergence of
trajectories from time-dependent simulations.
ENCORE includes three different methods for calculations of similarity measures between ensembles implemented in individual functions:
Harmonic Ensemble Similarity :
hes()Clustering Ensemble Similarity :
ces()Dimensional Reduction Ensemble Similarity :
dres()
as well as two methods to evaluate the convergence of trajectories:
Clustering based convergence evaluation :
ces_convergence()Dimensionality-reduction based convergence evaluation :
dres_convergence()
