title: Root mean square deviation probability analysis of molecular dynamics trajectories on DNA.
abstract: The comparison and detection of the commonalities and differences in multiple structural ensembles is an important step in the use of molecular simulations to gain insight into the conformation and dynamics of complex biomacromolecules. While the average structure is often employed as the representative of an ensemble of structures in such comparisons, dynamic molecular systems with multiple conformational substates call for a more accurate representation that captures the complete dynamical range of the ensemble. We present a probability analysis procedure based on the root-mean-square differences among the structural ensembles that efficiently and accurately performs the relevant comparison.
