The rietx manual

rietx is a Python package for Rietveld, Le Bail and Pawley refinement of powder diffraction data.

New to rietx

You know Rietveld refinement and want your first fit in rietx. Start with a Le Bail fit of a standard, then a full refinement.

Start

Coming from another code

You use TOPAS, GSAS-II or FullProf. See what rietx does the same, what it does differently, and how it was validated.

Switching

Supervising an agent

An agent runs the fits and you check them. See what to read in a report and when to stop a run.
