Indirect Inelastic Changes
- The Run button has been moved to be above the output options.
- The Run, Plot and Save buttons are disabled while processing or plotting is taking place.
- IqtFit and ConvFit have a new option to edit the _Results workspace. This option allows
the selection of two _Result workspaces (one containing the results of a sequential fit
for multiple spectra (1), and the other containing the results of a fit for a single
spectrum(2)). The algorithm IndirectReplaceFitResult
will replace the relevant data found in workspace (1) with the data found in workspace (2).
- The Fit Single Spectrum buttons on MSDFit, I(Q,t)Fit, ConvFit and F(Q)Fit are now disabled
during fitting.
- When the InelasticDiffSphere,
InelasticDiffRotDiscreteCircle,
ElasticDiffSphere or
ElasticDiffRotDiscreteCircle functions are selected in
the ConvFit tab, the Q values are retrieved from the workspaces, preventing a crash when plotting
a guess.
- The Plot buttons in MSDFit, I(Q,t)Fit, ConvFit and F(Q)Fit are disabled after a Run when the
result workspace only has one data point to plot.
- There is now an option to choose which output parameter to plot in MSDFit.
- An option to skip the calculation of Monte Carlo Errors on the I(Q,t) Tab has been added.
- During the calculation of Monte Carlo Errors, a progress bar is now shown.
- In the I(Q,t) Tab, it is now possible to select which spectrum you want to plot for Plot Spectrum.
- In the I(Q,t) Tab, it is now possible to select a range of spectra for a Tiled Plot. The interface
allows a maximum of 18 plots.
- The WorkspaceIndex and Q value in the FitPropertyBrowser are now updated when the Plot Spectrum
number is changed. This improvement can be seen in ConvFit when functions which depend on Q value
are selected.
- Fit and Fit Sequential in the Fit combobox above the FitPropertyBrowser are now disabled while
fitting is taking place.
- The option to choose which workspace index to Plot Spectrum for and from which output workspace
is now given in Elwin.
- ConvFit now allows the loading of Dave ASCII files which end with _sqw.dave.
- The AddWorkspace windows (opened from the Multiple Input tab) now stay open after adding a
workspace to the data table. This is found on the MSDFit, I(Q,t)Fit, ConvFit and F(Q)Fit
interfaces.
- It is now possible to load a Nexus file without it’s history on the Elwin interface by unchecking
the Load History checkbox.
- It is now possible to undock the mini-plots on the MSDFit, IqtFit, ConvFit and F(Q)Fit interfaces.
- The workspace(s) loaded into F(Q) Fit are checked for EISF or Width values, and an error message
is displayed if neither are present. This prevents an unexpected crash.
- The parameter values for a selected spectrum are now updated properly when a Fit is run using the
Fit String option in ConvFit.
- An unexpected crash is prevented when Plot Current Preview is clicked when no data is loaded. A
meaningful error message is now displayed.
- The Probability Density Functions (PDF) workspaces for the FABADA minimiser in ConvFit no longer
overwrite each other.
- Loading a resolution file before a reduced file in ConvFit no longer causes an unexpected error.
- A bug where fixed parameters don’t remain fixed when using the FABADA minimizer in ConvFit has been
fixed.
- The expression for the Fit type MSDYi in MSDFit was incorrect and has now been
corrected.
- The x-axis labels in the output plots for MSDFit are now correct.
- An unexpected error is now prevented when clicking Plot Guess from the Display combo box in
ConvFit without first loading a reduced file.
- The output workspace ending with _Results now contains workspaces with corrected names which
detail the fit functions used.
- Selecting multiple data using the All Spectra checkbox without first selecting a sample file used
to cause an unexpected error. This is now prevented. Meaningful error messages are also displayed
when a sample or resolution file are not selected.
- In the Elwin interface, the errors are now propagated correctly through to the workspace with
extension _elt.
- The HallRoss fit function was updated to have
in its formula.
The TeixeiraWater and ChudleyElliot fit
functions now have a functionDeriv1D method.
- A bug causing the output _Results workspace from a single fit to have an incorrect name has been
fixed.
- A bug causing the preview plot in Elwin not to update when changing the selected workspace has been
fixed.
- Fixed an issue on FQFit where a workspace with only one data point could be loaded.
- Added ‘Interpolation’ combobox to Calculate Monte Carlo Absorption. This allows the method of
interpolation to be selected. Allowed values: [‘Linear’, ‘CSpline’].
- Added ‘MaxScatterPtAttempts’ spinbox to Calculate Monte Carlo Absorption. This sets the maximum
number of tries to be made to generate a scattering point.
- In the Calculate Monte Carlo Absorption Tab, all of the options in the Monte Carlo section are now
read from an instrument parameter files once a file has been loaded.
- The option to choose which spectrum to Plot Spectrum for is now available in the
ContainerSubtraction tab and ApplyAbsorptionCorrections tab.
- Fixed a bug where ApplyAbsorptionCorrections would not apply corrections if the _Corrections group workspace
did not contain sample attenuation (_ass).
- Added ‘Default’ detector grouping option back into ISISEnergyTransfer for TOSCA, to allow a
default grouping using the grouping specified in the Instrument Parameter File.
- ISISEnergyTransfer now allows overlapping detector grouping.
- It is now possible to choose which spectrum to Plot Output for in the S(Q, w) tab.
- An automatic contour plot of rqw is now displayed in the S(Q, w) tab when a sample is loaded.
- Symmetrise tab has changed so you can no longer click the run button before preview, and
preview will not run even if clicked unless the max or min bars on the top graph have changed
from their default.
- A bug where the output reduced files had large file sizes depending on the size of the batch
being reduced from the ISISIndirectEnergyTransfer
algorithm on the ISISEnergyTransfer interface has been fixed. The
ISISIndirectEnergyTransferWrapper algorithm
should be used instead in order to avoid these large file sizes.
- A bug where using a cropped calibration file (from a previous run) on the ISISEnergyTransfer
interface would cause an error has been fixed.
- A bug where specifying a custom detector grouping for OSIRIS was not working has been fixed.
- A crash caused by data being loaded multiple times on the transmission tab has been fixed, as
part of this fix the preview now shows a preview of the plot on run being clicked and not
before as this was the cause of the issue.
- A bug caused by incorrect masked detectors during a reduction of an individual runs has been
fixed. This could sometimes cause unexpected peaks in the output plots.
- A bug caused by incorrect masked detectors during a reduction for a summed run has been fixed.
This would cause the summed runs intensity to be higher than that of the individual runs with
the same run numbers.
- It is now possible to produce a contour plot from the output on the Stretch Tab.
- There is no longer a plot output option for ‘Fit’ in the Quasi Tab. The graph ‘Fit.2’ is also
now plotted when you click Plot Current Preview.
- The sample logs are now copied over properly for the result workspace in the ResNorm tab.
- _sqw files can now be loaded as Vanadium in the ResNorm tab.
- In the Quasi tab, fit. 3 and diff. 3 are now stored in the fit workspaces. The probabilities
for 3 peaks is now available in the probability workspace.
- An unwanted ‘Fit’ plot is no longer plotted in ResNorm when you click Plot in the output options.
- Any zeros within the vanadium file are replaced with a substitute value of 10% the minimum
y value found within that file. This prevents infinity values being produced when dividing the
input file by the vanadium file.
- An unexpected error when using manual grouping has been fixed.
- BASISReduction user interface contains slightly different naming convention for selection of reflection and works for old and new DAS.
