Developer builds interactive GSAS-II-style Rietveld refinement tool with Claude to visualize pxrd parameters
Robert_Palgrave · x · 2026-09-24
Robert Palgrave found learning Rietveld refinement of powder XRD data hard because it takes time to grasp how each parameter affects the fit. So he built an interactive, GSAS-II-like tool using Claude Opus 5.5 that lets users tweak parameters manually and instantly see the effect on the model. It ships with preloaded datasets and can load CIF files or full GSAS-II projects, aiming to make this class of data analysis easier to learn.
