Note

These release notes were migrated from the retired Mantid wiki (archive.mantidproject.org).

Peak Processing Improvements

• You can now add peaks workspaces together using CombinePeaksWorkspaces

• You may also subtract peak workspaces using DiffPeaksWorkspaces

• IntegratePeaksMD can determine when the peak radius or background shell is falling off the detector edge

• SortHKL will now work with non-integer HKLs

• IndexPeaks improved to better handle peaks workspaces with peaks from several runs

ImageViewer

The MantidPlot ImageViewer , which was prototyped during the last iteration, is now fully operational and nearly feature-complete. Specific improvements include:

• Support for matrix workspaces (in addition to the event workspaces previously supported)

• “Immediate” rebinning of the X-axis in either Log or uniform bins

• Coordinated scrolling of the horizontal and vertical cuts along with the image

• Range control for the graphs of horizontal and vertical cuts

• “Two-sided” “psuedo-log” color scales to support negative intensities from subtracting workspaces

• More complete readout of equivalent units for pointed at features

See the ImageViewer page for specific improvements to this tool.

Other Improvements

• SumNeighbours will support detectors other than just rectangular detectors.

• Improve algorithms that set a conventional cell and TransformHKL

• Add monitor count to the single crystal peak object.

Defects Fixed

• Goniometer would not work with psi value loaded from nxspe file.
