WebFeb 21, 2024 · To my understanding only the Plus version allows for Rietveld refinement. An alternative would be to use one of the Highscore Plus COD database options that directly adds those phases. You can find a link here. Just make sure to select a year close to the version of Highscore as older versions aren't really supporting the new COD versions. http://prism.mit.edu/xray/documents/6c%20Fundamentals%20of%20Rietveld%20Refinement%20Additional%20Examples%20HSP%20v3%20revised%20July2012.pdf
