Thermo package (pyemma.thermo)

The thermo package provides functions to analyze data originating from potentially biased multi-ensemble MD-Simulations.

User-Functions

For most users, the following high-level functions are sufficient to estimate models from data.

estimate_umbrella_sampling(us_trajs, …[, …])	This function acts as a wrapper for tram(), dtram(), mbar(), and wham() and handles the calculation of bias energies (bias) and thermodynamic state trajectories (ttrajs) when the data comes from umbrella sampling and (optional) unbiased simulations.
estimate_multi_temperature(energy_trajs, …)	This function acts as a wrapper for tram(), dtram(), mbar, and wham() and handles the calculation of bias energies (bias) and thermodynamic state trajectories (ttrajs) when the data comes from multi-temperature simulations.
tram(ttrajs, dtrajs, bias, lag[, …])	Transition-based reweighting analysis method
dtram(ttrajs, dtrajs, bias, lag[, …])	Discrete transition-based reweighting analysis method
wham(ttrajs, dtrajs, bias[, maxiter, …])	Weighted histogram analysis method
mbar(ttrajs, dtrajs, bias[, maxiter, …])	Multi-state Bennet acceptance ratio
