 ``mdciao`` is a Python module that provides quick, "one-shot" command-line tools to analyze molecular simulation data using residue-residue distances. ``mdciao`` tries to automate as much as possible for non-experienced users while remaining highly customizable for advanced users, by exposing an API to construct your own analysis workflow.
