Diffraction Changes
Release 3.13.0
- LoadILLDiffraction is extended to apply vertical and horizontal tube alignment for D2B, based on the IPF.
- LoadILLDiffraction is modified to comply with the U-shape convention for tube numbering for D2B.
- PowderDiffILLDetEffCorr is extended to compute the detector efficiencies also for the 2-dimensional scanning diffractometer D2B at the ILL.
- PowderDiffILLDetEffCorr is extended to provide automatic masking of the pixels with spurious calibration constants.
- PowderDiffILLDetEffCorr will now ignore the last scan point data, if some of the input files have 26 points, instead of 25.
- PowderDiffILLDetScanReduction is extended to provide initial masking of the top and bottom parts of the tubes, and final masking of the 2D outputs.
- WANDPowderReduction performs powder diffraction data reduction for WAND² with calibration, monitor normalisation and background subtraction.
- New NOMAD instrument geometry for 2018 run cycle
- New POWGEN instrument geometry for 2018 run cycle
- New SNAP instrument geometry for 2018 run cycle with configuration for live data
- Changing settings while running methods on the PEARL object no
longer updates the default settings. Instead, initial settings are
taken as the default, and any changes are reverted back to the
default once the line they were made on has finished executing
- Focusing in texture-mode (160 banks) was enabled for GEM. The output
is saved to several formats:
- The three-column
.gem format
- The
.maud calibration file format, for conversion to d-spacing (uses a new algorithm
SaveGEMMAUDParamFile
- PDCalibration has major upgrades including making use of FitPeaks for the individual peak fitting
- StripPeaks has been adjusted to allow for removing peaks that have only 3 bins across them (decreased from 5 bins)
- AlignAndFocusPowder had a bug when binning in time-of-flight without using a property manager to specify the time-of-flight range. In other words: characterization files are no longer necessary.
- Improvements to the GSAS tab:
- GSASIIRefineFitPeaks is now run asynchronously in the GUI, so the
tab no longer locks when a refinement is run
- A Refine All button was added to run refinement on every run
loaded into the tab
- GSASIIRefineFitPeaks now supports Pawley refinement as well as Rietveld
- HDF5 is now the standard format for saving data from the GUI:
- The
.nxs file from the Focus tab is now saved in the Focus directory with all the other focus output
- New algorithm LoadDNSSCD to load multiple single crystal diffraction data files from the DNS instrument into MDEventWorkspace.
- New algorithms LoadWANDSCD and ConvertWANDSCDtoQ to load single crystal HB2C data and convert it to either Q-sample or HKL space.
- New algorithm IntegratePeaksProfileFitting to integrate peaks using 3D profile fitting in reciprocal space.
- New algorithm FindSatellitePeaks to predict the location of fractional satellite peaks using a set of nuclear peaks and a set of seed satellite peaks.
- New algorithm IndexSatellitePeaks to index satellite peaks found using the FindSatellitePeaks algorithm.
- SaveLauenorm now has input options for crystal system and reflection condition for lscale output instead of trying to determine from lattice parameters.
- New TOPAZ instrument geometry for 2018 run cycle
- CreatePeaksWorkspace now accepts MD workspaces as input.
- PeaksWorkspace has column added for the unique peak number so peaks can be found after sorting or filtering.
- StatisticsOfPeaksWorkspace has option to use a weighted Z score for determining which peaks are outliers and has a new output workspace for plotting intensities of equivalent peaks.
