This GUI was created in MATLAB and serves as an educational tool for both novice and experienced crystallographer, and as a quick tool to make crystallographic computations. This GUI allows the creation of stereographic projection as well as the individual computation of angles between planes and directions for all seven crystal systems. Those who work in preferred orientation of polycrystalline materials or single crystals might find this GUI useful. To view code, check MATLAB File...

An expert system for automated reduction of X-Ray diffraction data from macromolecular crystals, making use of existing software (CCP4, XDS, Phenix, CCTBX.)

xylib is a portable library for reading x-y data from powder diffraction, spectroscopy and other experimental methods. Supported formats: VAMAS, pdCIF, Bruker, Philips, Rigaku DAT, Sietronics CPI, DBWS/DMPLOT, Koalariet XDD and others.

This script can convert raw diffraction images to JPEG files. Support ADSC, MarCCD, Mar345, RAXIS and PILATUS, and can be run on Windows, Linux and Mac OS X.

NHWAVE is a non-hydrostatic wave model that is capable of simulating wave processes (dispersion, shoaling, refraction, diffraction and breaking) from deep water to nearshore.

X-ray diffraction data processing and visualization pipeline for Laue photo-crystallography

Matlab/Octave implementation of the Rigorous Coupled Wave Analysis

.... ===== Tonto is a free library dedicated to quantum crystallography and quantum chemistry. It can refine crystal structures using ab initio wavefunctions. It can also fit electronic wavefunctions to X-ray diffraction data. === PLEASE READ BELOW === An updated release 3.1 (revision 3800) has been made in the Files part. Various linux executables have also been uploaded so you don't need to compile. For non-standard jobs, or for bug-fixes, get the latest version on branches/tonto-3.2 using subversion, like this: svn checkout svn://svn.code.sf.net/p/tonto-chem/code/branches/tonto-3.2 tonto-3.2 DO NOT check out the head, it is too unstable at the moment.

The Diffraction Image Experiment Repository (DIMER) is an online archive for diffraction experiments, providing secure storage during analysis and publishing of experiments so they can be linked to, searched, and integrated into other databases.

...It allows the user to define any optical setup (composed typically of laser sources, mirrors, lenses, electro-optical modulators and detectors) and to compute the static laser field at any point. It uses a Hermite-Gauss modal decomposition to simulate diffraction limited optics. This tool is being developed mainly for simulation of large scale interferometers with resonant cavities used for the detection of gravitational waves.

Clip is an interactive program for simulation, indexing and refinement of Laue diffraction images.

DDM program is designed for crystal structure analysis from powder diffraction data by making use of either Rietveld or Derivative Difference Minimization (DDM) method. In the DDM method the refinement is aimed not at minimizing the absolute difference between the experimental and calculated profiles but at minimizing the oscillations (or curvature) of the difference curve. The squared values of the difference curve derivatives are used in DDM as a measure of the difference curvature. ...

The pySpec project is a set of data analysis routines written in python for analysis of x-ray diffraction data produced by the SPEC X-Ray Diffraction and Data Acquisition software. This repo has moved to : https://github.com/stuwilkins/pyspec

pyanpha is a shell-based program, which applies the multi-wavelength anomalous diffraction technique to Surface Diffraction. It enables one to calculate the phases of the structure factors of crystal truncation rods when anomalous scatterers are present in the thin film. Functionality extends to standalone simulations. It was coined pyanpha which is an acronym for PYthon ANomalous PHAsing and it is written in python.
