Home for GSAS-II: crystallographic and diffraction-based structural characterization of materials
A cross-platform, open-source library for the analysis of X-ray diffraction data.
library for reading files with x-y data from powder diffraction, spectroscopy, or other experimental methods
Qt6 PySide6 based GUI for the HEXRD library.
Scripts for building GSAS-II conda packages & binaries and dist location for downloading binaries

PDIndexer is a powder X-ray / neutron diffraction analysis tool: it displays diffraction profiles, overlays the calculated diffraction lines of known crystals, fits peaks to refine lattice constants, and estimates pressure from the equations of state of standard materials.
A versatile and interactive package for solving crystal structures from powder diffraction data
Accelerated molecular crystal structure determination from powder diffraction data
Powder X-ray diffraction Rietveld refinement using FullProf.
IPAnalyzer converts Debye-Scherrer ring images from imaging plates and flat-panel detectors into 1D diffraction profiles, calibrates the measurement geometry, and works with PDIndexer.
R package: wrapper for the C++ library `xylib`
Online calculator of partial radial distribution function (PRDF), global RDF, and XRD/ND patterns for crystal structures.
Calculate powder XRD patterns based on XRDCalculator in pymatgen, but using Rust for certain parts, making it about > 10x faster.
GSAS-II Tutorial web pages & tutorial data
Tools for XRD and CMWP analysis
A program for plotting powder diffraction patterns and background subtraction
Python library for XrdPatterns including file import, file export and postprocessing functionalities
Generic ML prediction of lattice parameters for PXRD
