PyFAI is using FabIO everywhere access to a 2D images is needed. The fabio_viewer is also a lightweight convenient viewer for diffraction images. It has been described in doi:10.1107/S0021889813000150
The X-ray Fluorescence Toolkit provides convenient tools for HDF5 file browsing and mask drawing. It has been described in doi:10.1016/j.sab.2006.12.002
Client-server program to perform azimuthal integration online. Developed for the SNBL and Dubble beamlines by Vadim DIADKIN and available from this mercurial repository.
Dahu is a lightweight plugin based framework available from this git repository. Lighter then EDNA, it is technically a JSON-RPC server over Tango. Used on TRUSAXS beamline at ESRF (ID02), dahu uses pyFAI to process data up to the kHz range.
Graphical user interface for high-pressure diffraction, developed at the APS synchrotron by C. Prescher and described in: doi:10.1080/08957959.2015.1059835
The amount of data collected during synchrotron X-ray diffraction (XRD) experiments is constantly increasing. Most of the time, the data are collected with image detectors, which necessitates the use of image reduction/integration routines to extract structural information from measured XRD patterns. This step turns out to be a bottleneck in the data processing procedure due to a lack of suitable software packages. In particular, fast-running synchrotron experiments require online data reduction and analysis in real time so that experimental parameters can be adjusted interactively. Dioptas is a Python-based program for on-the-fly data processing and exploration of two-dimensional X-ray diffraction area detector data, specifically designed for the large amount of data collected at XRD beamlines at synchrotrons. Its fast data reduction algorithm and graphical data exploration capabilities make it ideal for online data processing during XRD experiments and batch post-processing of large numbers of images.
Graphical user interface for small angle diffusion, developed at the Petra III synchrotron by G. Benecke and co-workers and described in doi:10.1107/S1600576714019773
X-ray scattering experiments at synchrotron sources are characterized by large and constantly increasing amounts of data. The great number of files generated during a synchrotron experiment is often a limiting factor in the analysis of the data, since appropriate software is rarely available to perform fast and tailored data processing. Furthermore, it is often necessary to perform online data reduction and analysis during the experiment in order to interactively optimize experimental design. This article presents an open-source software package developed to process large amounts of data from synchrotron scattering experiments. These data reduction processes involve calibration and correction of raw data, one- or two-dimensional integration, as well as fitting and further analysis of the data, including the extraction of certain parameters. The software, DPDAK (directly programmable data analysis kit), is based on a plug-in structure and allows individual extension in accordance with the requirements of the user. The article demonstrates the use of DPDAK for on- and offline analysis of scanning small-angle X-ray scattering (SAXS) data on biological samples and microfluidic systems, as well as for a comprehensive analysis of grazing-incidence SAXS data. In addition to a comparison with existing software packages, the structure of DPDAK and the possibilities and limitations are discussed.
EDNA is a framework for developing plugin-based applications especially for online data analysis in the X-ray experiments field (http://edna-site.org) A EDNA data analysis server is using pyFAI as an integration engine (on the GPU) on the ESRF BioSaxs beamline, BM29. The server is running 24x7 with a processing frequency from 0.1 to 10 Hz.
The Library for Image Acquisition is used at many European synchrotrons to control various types of camera. A pyFAI plugin is available to integrate images on the fly without saving them.
TODO ... Developed at IBS (Grenoble) by N. Coquelle
A Python library for reduction of 2D grazing-incidence X-ray scattering data developped at ESRF (ID13) by Thomas DANE.
Grazing-incidence X-ray scattering techniques (GISAXS, GIWAXS/GID) allow the study of thin films on surfaces that would otherwise be unmeasurable in standard transmission geometry experiments. The fixed incident X-ray angle gives rise to a distortion in the diffraction patterns, which is extreme at wide-angles. The pygix library provides routines for projecting 2D detector images into corrected reciprocal space maps, radial transformations and line profile extraction using pyFAI’s regrouping functions.

Developed by the Billinge Group, this commercial software is described in arXiv 1402.3163 (2014)
xPDFsuite is an application that facilitates the workflow of atomic pair distribution function analysis of x-ray diffraction measurements from complex materials. It is specially designed to help the scientist visualize, handle and process large numbers of datasets that is common when working with high throughput modern synchrotron sources. It has a full-featured interactive graphical user interface (GUI) with 3D and 3D graphics for plotting data and it incorporates a number of powerful packages for integrating 2D powder diffraction images, analyzing the curves to obtain PDFs and then tools for assessing the data and modeling it. It is available from diffpy.org <http://diffpy.org>.
