Classification: 23.

External routines: A VMD installation (http://www.ks.uiuc.edu/Research/vmd/)

Nature of problem:
Extract thermodynamic data and build a kinetic model of a given process simulated by metadynamics or molecular dynamics simulations, and provide this information on a dual representation that allows navigating and exploring the molecular structures corresponding to each point along the multidimensional free energy hypersurface.

Solution method:
Graphical-user interface linked to VMD that
  1. clusterizes the simulation trajectories in the space of a set of collective variables and assigns each frame to a given microstate,
  2. determines the free energy of each microstate by a weighted histogram analysis method, and
  3. identifies the most relevant free energy wells (kinetic basins) by diagonalization of the rate matrix followed by a commitor analysis.
