This is a basic computer program (coded in Python) to simulate possible unit crystal cell length (a), Miller indices - {h, k, l} and interplanar spacing (d) for cubic crystals from observed (experimental) X-ray diffraction (XRD) angle, 2-theta. It can simulate all these possible crystal lattice parameters for cubic crystal systems between the given 2–theta values within the range of specified cell length (a) limits. 1.

Crystalsim is a simple freeware program with a neat graphical user interface for X-ray diffraction (XRD) data analysis . It can simulates all possible {hkl} planes data for the selected crystal. Crystallographic Information File (.cif) can also be used. Analyze both powder diffraction and single crystal data . Indexed at International Union of Crystallography (IUCR). Crystalline lattice parameters such as ‘a’, ‘b’, ‘c’ as well as interfacial angles such as alpha, beta, gamma can also be entered manually. ...

LaueTools is an open-source project for white beam Laue x-ray microdiffraction data analysis including tools in image processing, peaks searching & indexing, crystal structure solving (orientation & strain) and data & grain mapping visualisation. Python 3 Code and new features are now at: https://gitlab.esrf.fr/micha/lauetools

This is an implementation of post-process phonon analyzer, which calculates crystal phonon properties from input information calculated by external codes, e.g., first-principles calculation code.

Computational package to study transition metal atoms in surfaces, focusing on the effects of crystal field, spin orbit coupling and electronic interactions. Inputs are written in an user friendly interface, and creates a pdf and graphics with the results.

**(9 march 2016) this project is continued on github : http://jaapkroe.github.io/polypy ** Python script to analyze (shortest-path) rings in structures read from xyz-files. It can be useful for example to identify defects in crystal structures or molecules.

...It offers new algorithm for concurrent peak deconvolution at different heating rates and provides full kinetic analysis of these data, including isoconversional methods for Ea, determination of reaction model and full kinetic triplet, Avrami coefficients, and dimensionality of crystal growth for reactions in the solid state. The project is currently in alpha stage, where individual modules will be provided for data analysis. The modules for peak deconvolution, peak profile analysis and determination of Ea and lnA will be provided first. Full GUI will be provided in beta stage. Due to computational limitations, the code is partly programmed in Python and partly in R. ...

This program allows to design a x-ray spectrometer. A particular aspect is the large options of crystal shape. The source, crystal and detector are freely positionnable in 3D space (allowing to check the effect of misalignment)

Analysis of HYDROgen BONding NETworks in protein crystal structures.

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.
