alchemlyb: the simple alchemistry library
=========================================

|doi| |docs| |build| |cov| |anaconda|

**alchemlyb** makes alchemical free energy calculations easier to do
by leveraging the full power and flexibility of the PyData stack. It
includes:

1. Parsers for extracting raw data from output files of common
molecular dynamics engines such as `GROMACS`_, `AMBER`_, `NAMD`_
and `other simulation codes`_.

2. Subsamplers for obtaining uncorrelated samples from timeseries data
(including extracting independent, equilibrated samples
[Chodera2016]_ as implemented in the pymbar_ package).

3. Estimators for obtaining free energies directly from this data, using
best-practices approaches for multistate Bennett acceptance ratio (MBAR)
[Shirts2008]_ and BAR (from pymbar_) and thermodynamic integration (TI).
