This is an fast implementation of the weighted histogram analysis method written in Rust. It allows the calculation of multidimensional free energy profiles from umbrella sampling simulations.

Features

Fast, especially for small systems
Multidimensional
Unit tested

TODO

Multithreading (?)
Error analysis / bootstrapping
Better error messages during file I/O
