The Excitations group uses a wide range of software for data reduction, visualisation and analysis. The most commonly used programs are installed and available on the virtual machines of the IDAaaS system:

If you wish to use the software on your own computer, all of these ​packages are freely available, either from their own dedicated website (which will include a user manual), or from your instrument scientist.

Software home pages

Mantid - a platform for visualization, reduction and transformation of neutron and muon data. Scripting in Python. Open source.​

Within Mantid there are several specific tools that are regularly used on the group's instruments:

Other useful tools accessed from the main menu bar in Mantid are:
  • Pychop - for flux and resolution calculatoins (accessed via "Interfaces" -> "Direct" menu)
  • QECoverage - to calculate |Q| and energy region covered by detectors for a given Ei or Ef (accessed via "Interfaces" -> "Utility" menu)
  • TofConverter - calculate units conversion between time-of-flight, d-spacing, energy transfer, Q, wavelength, etc. (accessed via "Interfaces" -> "Utility")​

Horace - provides generation, visualisation, simulation and fitting of large 4-dimensional datasets obtained by making multiple measurements of a single crystal with varying sample orientation or incident energy. Matlab based.

Tobyfit - Tobyfit is a program for simulation and least squares fitting of single crystal neutron scattering data, incorporating instrument resolution. The latest version of this software runs in Matlab with a graphical user interface. 

PACE - Proper Analysis of Coherent Excitations will be a software application that enables a step change in the rapidity and quality of analysis of neutron experiments on the ISIS spectrometers in the Excitations Group.​ 

Non-ISIS software used by the group

MSlice - visualisation of single crystal data from a single run. Matlab based, although a standalone version also available.

DAVE - IDL implmentation of MSlice (as well as other modules for TAS, SANS, Spin-Echo, etc.), which is available as either an IDL module, or an exectutable.

Legacy code and manuals
