Hello,
We are proud to announce version 6.11.0 of Mantid. Installation packages can be found on our download page along with updated instructions for installing the latest release via Conda. You can also access the source code on the GitHub release page.
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 (seen in the figure above). - 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.
Please take a look at the release notes, which are filled with details of all the changes and improvements in many other areas. The development team has put a great effort into making all of these improvements and we would like to thank all of our beta testers for their time and effort helping us to make this another reliable version. Thank you to everyone that has reported any issues to us and please keep on reporting any problems you have on our forum or by email on mantid-help@mantidproject.org.
Kind regards,
The Mantid Team
