Mantid 6.10.0 Release Notes

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 v1 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 v1, FlipperEfficiency v1 and HeliumAnalyserEfficiency v1.

• Improvements to the way Mantid handles event compression. The algorithm CompressEvents v1 now has the ability to combine events together in logarithmically increasing size groups. We re-implemented LoadEventNexus when specifying the CompressTolerance (the execution time of LoadEventNexus is generally longer, but workflows using CompressEvents generally run faster).

• New option to find peaks using the ratio of variance/mean in FindSXPeaksConvolve v1 - 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 Elwin Tab of 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 provides better descriptions of what the interfaces do.

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.
