Welcome !

This experimental software repository provides a simple way to install scientific software for the neutron scattering community.

Note: we only support 64 bits, mostly Debian-based distributions.
Debain 8-9-10 Jessie/Buster, Mint 16-19 Ubuntu 14.04, 16.04, 18.04 are supported.
RedHat distributions support is limited (see below)

Configuration for Debian distributions (Ubuntu, Mint, ...)

Software SourcesTo use this repository, open the Software Sources settings (from e.g. Synaptic, Ubuntu Software Center or System Settings) and select the Other Software tab, then press the 'Add...' button and enter 'deb stable main'

You can also open a terminal and type:
for a Debian Jessie (8)/Ubuntu trusty (14.04) system:
% cd /etc/apt/sources.list.d
% sudo wget % sudo apt-get update
for a Ubuntu/xenial (16.04)/Mint 16-17 system:
% cd /etc/apt/sources.list.d
% sudo wget % sudo apt-get update
for a Ubuntu/bionic (18.04)/Debian Buster/Sid (9-10)/Mint 18-19 system:
% cd /etc/apt/sources.list.d
% sudo wget % sudo apt-get update
All packages from the software repository are then available from e.g. Synaptic, Aptitude, Ubuntu Software Center, and basically all 'apt' clients.

To install a package from the command line, use
% sudo apt-get install <package_name>
Alternatively, you can also download manually each Debian package from:
Some packages rely on others, and you might need to resolve all dependencies yourself. This is automatically done by Apt-clients and GDebi.

To install a single package, use:
# sudo dpkg -i <package_name-version.deb>
# gksudo gdebi-gtk <package_name-version.deb>
# sudo gdebi <package_name-version.deb>
NOTE: Many Debian packages have been created with the excellent Debreate.

BigDFT is a DFT massively parallel electronic structure code

BigDFT is a DFT massively parallel electronic structure code (GPL license) using a wavelet basis set. Wavelets form a real space basis set distributed on an adaptive mesh (two levels of resolution in our implementation). GTH or HGH pseudopotentials are used to remove the core electrons. Thanks to our Poisson solver based on a Green function formalism, periodic systems, surfaces and isolated systems can be simulated with the proper boundary conditions.
Pseudo potentials are included in the package. Tutorials and Manuals are in /usr/share/doc/bigdft.
On a multicore machine (SMP) you do not need MPI, as OpenMP will use available CPU's. Just launch 'bigdft', not 'mpirun -np N bigdft'.

DAVE - Data Analysis and Visualization Environment (neutron scattering)


by Richard Azuah, NIST

License: NIST
DAVE is an integrated environment for the reduction, visualization and analysis of inelastic neutron scattering data. It is built using IDL (Interactive Data Language) from ITT Visual Information Solutions,* which is a cross-platform application development tool with built-in graphics. All efforts have been made to ensure that DAVE is supported on Linux, Windows and MacOS X. It is available at no cost to users in two forms. The first is as a binary executable with an embedded IDL runtime license which can be used by anyone running on any of the three supported operating systems. In addition, for those who have an IDL development license, the complete source code for DAVE is also available.

 The main objective of DAVE is to provide a user friendly tool for scientists involved in neutron scattering research to quickly reduce, visualize and interpret their data. Currently, much progress has been made towards achieving this goal even though a lot still remains to be done. Support for several neutron scattering spectrometers at NCNR and PSI is included.

Frida (Fast reliable interactive data analysis) is a versatile data analysis program with special routines for inelastic neutron scattering.

 It has been written for the analysis of inelastic neutron scattering data, and it contains highly specialized routines for this purpose. Its data model, however, is abstract and generic so that Frida can be applied to whatever data of the form y(x,z0,z1,...).

 Frida's main capabilities are:

    Import/export tabular data from/to various formats.
    Reorganize, bin, sort, clone data.
    Perform mathematical operations on the data.
    Automatically document all data manipulations.
    Fit the data with user-defined functions.
    Plot data and functions, generating publication-grade PostScript graphics.

 Besides, Frida is also a powerful pocket calculator.

 Frida is operated through a command-line interface. Commands are cryptic. Everything is designed to offer a maximum of computational power and flexibility for a minimum of typing. Learning Frida is not easy, but rewarding.

 Some example data files and documentation is available in /usr/local/share/frida

License: Unspecified (ILL,LLB)
The FullProf Suite (for Windows and Linux) is formed by a set of crystallographic programs (FullProf, WinPLOTR, EdPCR, GFourier, etc...) mainly developed for Rietveld analysis (structure profile refinement) of neutron (constant wavelength, time of flight, nuclear and magnetic scattering) or X-ray powder diffraction data collected at constant or variable step in scattering angle 2theta.

 The different programs can be run either in stand alone form (from a console window or clicking directly in a shortcut) or from the interfaces WinPLOTR and/or EdPCR.

 The programs within the FullProf Suite are distributed in the hope that they will be useful, but WITHOUT ANY WARRANTY of being free of internal errors. In no event will the authors (or their institutions) be liable to you for damages, including any general, special, incidental or consequential damages arising out of the use or inability to use the programs (including but not limited to loss of data or data being rendered inaccurate or losses sustained by you or third parties or a failure of the program to operate with any other programs). The authors are not responsible for erroneous results obtained with the programs.

GenX is a versatile program for fitting X-ray and neutron reflectivity data (scattering)


by Matts Bjorck <>

License: GPL3
GenX is a versatile program using the differential evolution algorithm for fitting, primarily, X-ray and neutron reflectivity data, lately also surface x-ray diffraction data. The differential evolution algorithm is a robust optimization method which avoids local minima but at same is a highly effective. GenX is written in python and uses the wxpython package for the Graphical User Interface (GUI) Screenshot. A model to fit is defined either through a GUI plug-in or via a python script. The possibility to script everything makes it easy to develop completely new fitting model. Clearly, GenX is extremely modular, making it possible to extend the program with models and plug-ins for most fitting problems. At the present GenX is shipped with models for x-ray and neutron specular reflectivity, off-specular x-ray reflectivity and surface x-ray diffraction. A detailed description, of a older version, has been published in J. Appl. Cryst. 40, 1174 (2007).

GRASP - graphical inspection, analysis and reduction of multi-detector data produced by the Small-Angle Neutron Scattering (SANS) instruments


by Charles Dewhurst <>

License: Unspecified (ILL)
GRASansP" is a Matlab application designed for the graphical inspection,  analysis and reduction of multi-detector data produced by the Small-Angle Neutron  Scattering (SANS) instruments of the Institut Laue-Langevin (ILL).  GRASansP  deals with many of the diverse requirements for analysis and reduction of SANS  data using a general set of tools and reduction algorithms.  Data from the two  ILL SANS instruments, D11 and D22, as well as SANS instruments at some other  neutron sources, are currently catered for in the GRASansP package.  In principle  the architecture and coding of GRASansP combined with the matrix handling abilities,  graphics and other advantages of the Matlab' environment should allow continued  development of this software and be able to provide more general aspects of  multi-detector and complex data set handling. The drive for producing such a  suite of software came from the overwhelming need for a modern, complete and  general-purpose package to deal with typical procedures required for analysis  of two-dimensional SANS multidetector data.  By it's very nature, two-dimensional  data is often best appreciated in a graphical form.  The birth of GRASansP came  from the need for graphical inspection and ability to be able to quickly process  and extract the scattered intensity, I(q), as a function of position on the  multidetector (qx,qy) or as a function of sample environment conditions from a  series of many measurement runs (e.g. temperature sweep, rocking curve etc.).   This, combined with an interest in scientific software development and the abilities  of the Matlab environment have brought GRASansP into it's present state.
 The installation location is /usr/local/grasp, which contains documentation.
 Examples can be found at
 To use this software, you need to install the Matlab Compiler Runtime in /opt/MATLAB,  so that you should have a directory /opt/MATLAB/MATLAB_Compiler_Runtime/v713/.

GSAS - General Structure Analysis System (neutron/x-ray diffraction)


by Allen C. Larson and Robert B. Von Dreele, B. H. Toby

License: NIST

GSAS (General Structure Analysis System) is a comprehensive system for the refinement of structural models to both x-ray and neutron diffraction data. The GSAS package can be used with both single-crystal and powder diffraction data (Rietveld analysis), even both simultaneously. Neutron data can be either from single-wavelength instruments, or for those a bit more masochistic, time-of-flight instrumentation. Up to 99 different sets of data can be modeled using mixtures of up to 9 different phases.
 GSAS has been created by Allen C. Larson and Robert B. Von Dreele of Los Alamos National Laboratory. Executable versions of GSAS are distributed more-or-less freely (see the friendly message from the Regents of the University of California, below), but the source code is not distributed (don't complain to me on this one, I agree with you).

Neutrons4Science offers a set of multiplatform and interactive 3D animations for the education (neutron scattering)


by Alain Filhol <>

License: ILL, Ipter
Enter the world of neutrons! They are a powerful and highly acclaimed tool not only for the study of condensed matter (the world we live in) but also for confirming our current understanding of physics. What's more, you don't even need to be a scientist to use Neutrons4Science. Just be curious!
 Neutrons and protons are elementary particles constituting the nucleus of atoms. The neutron has no electric charge but has a spin and a magnetic moment. Neutron beams - like beams of X-rays, electrons or muons - are valuable tools for studying the multitude of materials that surround us in our daily lives (alloys, magnets, superconductors, polymers, colloids, proteins, biological systems, ...). However, the way neutrons interact with matter is quite unique and, as a result, it can often reveal to us what is normally hidden. With Neutrons4Science you can discover one of the many types of neutron spectroscopy.
 The neutron also answers questions on the very foundations of physics, helping us to solve some of the great mysteries of the universe (Is the Grand Unified Theory valid? Is there a fifth fundamental force? ...) As an example, Neutrons4Science gives you insights to a brand new method of neutron spectroscopy that takes advantage of the quantum states of this light neutral particle.
 Neutrons4Science lets you experience neutron science through three interactive 3D animations:
 * ThALES: Use a neutron spectrometer (ThALES) as if you were performing a real experiment.
 * Magnons: Discover the spin waves that exist inside magnetic materials and understand how ThALES can observe them.
 * GRANIT: Discover an innovative gravitational spectrometer (GRANIT) based on neutron quantum states in a gravitational field."
 These three educational animations were developed with the help of scientists at the "Institut Laue-Langevin", one of the world's flagship facilities for neutron science.

PyHST2 Hybrid distributed code for high speed tomographic reconstruction with iterative reconstruction and a priori knowledge capabilities. PyHST2 (formerly known as PyHST) has been engineered to sustain the high data flow typical of the third generation synchrotron facilities (10 terabytes per experiment) by adopting a distributed and pipelined architecture. The code implements, beside a default filtered backprojection reconstruction, iterative reconstruction techniques with a-priori knowledge. The latter are used to improve the reconstruction quality or in order to reduce the required data volume and reach a given quality goal. The implemented a-priori knowledge techniques are based on the total variation penalisation and a new recently found convex functional which is based on overlapping patches.

SASfit has been written for analyzing and plotting small angle scattering data. It can calculate integral structural parameters like radius of gyration, scattering invariant, Porod constant. Furthermore it can fit size distributions together with several form factors including different structure factors. Additionally an algorithm has been implemented, which allows to simultaneously fit several scattering curves with a common set of (global) parameters. This last option is especially important in contrast variation experiments or measurements with polarised neutrons. The global fit helps to determine fit parameters unambiguously which by analyzing a single curve would be otherwise strongly correlated. The program has been written to fulfill the needs at the small angle neutron scattering facility at PSI ( The numerical routines have been written in C whereas the menu interface has been written in tcl/tk and the plotting routine with the extension blt.

License: GPL 3
SIESTA is both a method and its computer program implementation, to perform efficient electronic structure calculations and ab initio molecular dynamics simulations of molecules and solids. SIESTA's efficiency stems from the use of strictly localized basis sets and from the implementation of linear-scaling algorithms which can be applied to suitable systems. A very important feature of the code is that its accuracy and cost can be tuned in a wide range, from quick exploratory calculations to highly accurate simulations matching the quality of other approaches, such as plane-wave and all-electron methods.
The possibility of treating large systems with some first-principles electronic-structure methods has opened up new opportunities in many disciplines. The SIESTA program is distributed freely to academics and has become quite popular, being increasingly used by researchers in geosciences, biology, and engineering (apart from those in its natural habitat of materials physics and chemistry). Currently there are several thousand users all over the world, and the paper describing the method (J. Phys. Cond. Matt. 14, 2745 (2002)) has received more than 6000 citations so far.

SpinWave - An easy-to-use and versatile software to calculate spin waves in any arbitrary magnetic lattice

Sylvain Petit, LLB CEA/Saclay

An easy-to-use and versatile software to calculate spin waves in any arbitrary magnetic lattice

Since the 1950’s, spin wave theory has been of fundamental importance in condensed matter physics. Spin waves are obtained from the linearization of the equation of motion, and can be seen as precession modes of the magnetically ordered structure, with typical energies of a few meV (or THz). Spin wave dispersions are routinely measured by neutron spectroscopy, and provide information about the coupling between spins and magnetic anisotropy parameters.

A spin wave calculating code, SpinWave, has been developed at the Laboratoire Léon Brillouin and is now freely available.

vDiffraction - This game is a fun way to discover the world of crystals and their symmetries through diffraction.


Alain Filhol <>

License: GPL2
Crystals are characterised by the fact that their constituents are arranged in a highly ordered structure. This internal order and its symmetry is clearly visible in the diffraction patterns produced by any crystal. It is this symmetry which is also gives crystals their often amazing shapes, making them highly prized by rockhounds. Whether you are a senior scientist, a student, or just curious about science, vDiffraction is a serious game that will let you try your hand at crystal diffraction so that you can begin to understand how scientists identify the symmetry characteristics of a crystal. This is the first, crucial step towards understanding the atomic and molecular structure of a crystalline material, in other words what type of atoms and molecules make up the crystal and how they are organised.

Using a Three Axis Spectrometer (TAS) is not easy since one has constantly translate parameters from real space to reciprocal space and vice versa
 The goal of vTAS is to provide an interactive and graphical display of both the instrument configuration and the corresponding measured space thus making easier the understanding of the behavior of the instrument and its limits.
 vTAS supports both the classical TAS geometry and the multiplexed geometry of FLATCONE. Other geometries are available through the vTAS suite described below.
 Simulation mode: vTAS allows experimentation with sample parameters, for example the Miller indices of the unit cell, whilst maintaining a representation of the instruments physical state, for example the location of the walls around the instrument, and its angular limits.
 The instrument resolution function is computed using the Cooper Nathan's method. A yet untested McStas like Monte Carlo approach is also available but for the bundled version only.
 Data viewer mode: vTAS is capable of reading ILL TAS data files. It displays both the data and the corresponding instrument configuration.

wcs2kml - Converts astrophysical images into a Sky in Google Earth friendly format

License: Apache 2
Professional astronomers typically store their imaging data in a binary format called FITS that has internal headers known as a WCS (World Coordinate System) that specify the location of the image on the sky.

This project consists of an API and several tools for converting FITS images with WCS information into imagery that can be viewed directly in Sky in Google Earth.

The conversion involves warping the input image from its native spherical coordinate system to the lat-long coordinate system and writing out an accompanying KML document describing the location of the image on the sky.

This was compiled from the original wcs2kml source code, with a few patches to adapt to libpng16. Source code is included as well as Makefile in /usr/share/doc/wcs2kml
