ReX is a powder diffraction analysis software based on the Rietveld method, providing a user-friendly environment to perform quantitative evaluation of powder data. ReX offers a flexible parameter-based architecture for the optimization of structural and microstructural related quantities, coupled with an intuitive and modern user interface; specifically oriented to beginners and non-specialist, can also be used by expert powder diffractionists in addition to more specialized packages.

You can get the latest ReX version from the download┬ápage – the documentation is still a work in progress but already includes some useful tutorials.
