Release v6.11.0
We are proud to announce version 6.11.0 of Mantid.
In this release we gave extra attention to fixing bugs and improving algorithms (for example by making them run faster or use less memory). We also added several new algorithms. These are the highlights for this release:
- There is a new Deprecation Policy for Mantid. One of the main changes is that we will deprecate algorithms that have not been used for 3 years or more.
- For single crystal diffraction, we added a new algorithm
FindMultipleUMatrices
to find multiple UB matrices when given lattice parameters for sample with multiple domains or spurious peaks. - Also for single crystal diffraction,
IntegratePeaksSkew
is better at determining background bins by minimising third-moment (skew). This is achieved by forcing skew > 0 (minimum skew we would expect in background). This change stops peak mask ofIntegratePeaksSkew
including too many pixels due to small diffuse scattering. - For powder diffraction, the algorithms
AlignAndFocusPowder
,AlignAndFocusPowderFromFiles
,SNSPowderReduction
andLoadEventAndCompress
were updated to use logarithmic compression, which uses less memory. - For reflectometry, we added a new algorithm
PolarizationEfficienciesWildes
for calculating the efficiencies of the polarizing components of an instrument with two flippers. This algorithm implements the approach from the A. R. Wildes 2006 paper doi: 10.1080/10448630600668738. - For SANS, we added new algorithm
PolarizerEfficiency
for calculating the efficiency of a polariser. - For Inelastic, renamed tabs of
QENS Fitting
fromMSD Fit
,I(Q,t) Fit
,ConvFit
andF(Q)
toMSD
,I(Q,t)
,Convolution
andFunction(Q)
respectively. - For Inelastic, the
Elwin Tab
ofData Processor Interface
now includes access to the Slice Viewer or 3D Plot from the output plot widget of the output workspaces containing more than 1 histogram. - Again for Inelastic,
QENS Fitting Interface
now allows loading a_Result
workspace from theI(Q, t)
fitting tab into theFunction (Q)
fitting tab if one of the fit parameters isA0
. - Finally, for developers, the Mantid developer environments are now created using a new
mantid-developer
Conda meta-package, hosted on our Conda channel. This change does not affect users but greatly simplifies our development process, as package dependencies are now automatically sorted on different operating systems.
These are just some of the many improvements in this release, so please take a look at the release notes, which are filled with details of the important changes and improvements in many areas. The development team has put a great effort into making all of these improvements within Mantid, and we would like to thank all of our beta testers for their time and effort helping us to make this another reliable version of Mantid.
Throughout the Mantid project we put a lot of effort into ensuring Mantid is a robust and reliable product. Thank you to everyone that has reported any issues to us. Please keep on reporting any problems you have, or crashes that occur on our forum.
Installation packages can be found on our download page which now links to the assets on our GitHub release page, where you can also access the source code for the release.

Release v6.10.0
We are proud to announce version 6.10.0 of Mantid.
In this release, we changed the way files are loaded into Mantid: On ISIS Data Analysis as a Service Platform (IDAaaS), loading files will look into the instrument data cache path /data/instrument first before looking for the file on the data archive. This change will speed up loading raw data files on IDAaaS, especially for users who do not have access to the data archive or users whose instrument data is not reliably accessed from the archive. Other important highlights include:
- New algorithm
IntegratePeaks1DProfile
to integrate single-crystal Bragg peaks in a workspace with an x-unit of TOF adapted from an algorithm in SXD2001 by Gutmann, M. J. (2005). - New algorithms for supporting the polarised SANS data reduction
DepolarizedAnalyserTransmission
,FlipperEfficiency
andHeliumAnalyserEfficiency
. - Improvements to the way Mantid handles event compression. The algorithm
CompressEvents
now has the ability to combine events together in logarithmically increasing size groups. We re-implementedLoadEventNexus
when specifying theCompressTolerance
(the execution time ofLoadEventNexus
is generally longer, but workflows usingCompressEvents
generally run faster). - New option to find peaks using the ratio of variance/mean in
FindSXPeaksConvolve
- this is a peak finding criterion used in DIALS software (Winter, G., et al. Acta Crystallographica Section D, Structural Biology 74.2 (2018): 85-97). - New detector grouping options on the Indirect Diffraction Interface (including All, Groups, Custom and File options).
- New way to easily load multiple files into the Elwin Tab of the Inelastic Data Processor Interface.
- The Inelastic Data Analysis Interface has been renamed to the Inelastic QENS Fitting Interface and the Inelastic Data Manipulation Interface has been renamed to the Inelastic Data Processor Interface. The new names provide better descriptions of what the interfaces do.

Release v6.9.1
This is a patch release that corrects some significant issues in version 6.9.0.
The changes are:
- A fix to stop workbench freezing when plotting data from a workspace that is changing (e.g plotting live data)
- Removed slit lookup that was specific to OFFSPEC in
ReflectometryReductionOneLiveData
as it is no longer required and was causing regular crashes when running live data on OFFSPEC. - Fixed a bug in Elwin Tab of Data Manipulation Interface where changing integration range with the sliders did not change default integration range.
- Add sample log values to the live data workspace before the instrument is loaded in
ReflectometryReductionOneLiveData
to ensure log values are available when setting the detector positions. - Fixed a crash when using multiple Indirect or Inelastic interfaces. This crash was present on the Bayes Fitting interface, but could also be replicated elsewhere.

Release v6.9.0
We are proud to announce version 6.9.0 of Mantid.
This release includes a wide array of updates, bugfixes, and new features.
We would like to highlight the following improvements:
- The performance of the
LoadAscii
algorithm has significantly improved, achieving at least a one order of magnitude speedup. - The

algorithm has been added for integrating single-crystal Bragg peaks in a workspace with an x-unit of TOF using a shoebox. - The
FindPeaksConvolve
algorithm has been added for 1D peak finding, and is available in theFitPropertyBrowser
. It provides improved peak finding when compared to theFindPeaks
algorithm. - The option to open the sliceviewer directly from the Indirect and Inelastic interfaces for the output data has been added.
