Inelastic Data Manipulation Testing¶
Prerequisites
Download the ISIS Sample Data
Make sure that the data set is on your list of search directories
Elwin tab¶
Time required 3 - 5 minutes for each
1. Direct data¶
Go to
Interfaces
>Inelastic
>Data Manipulation
Go to the
Elwin
tabClick on
Add Workspaces
, a dialog window should prompt.Enter
MAR27691_red.nxs
inInput file
. The table of the dialog should be populated with theMAR2791_red
workspace.Select the workspace from the table and click on
Add Data
. Close the dialog.Back on
Elwin
tab, clickRun
- this should produce 3 new workspaces_elf
,_eq
and_eq2
Open the
Add Workspaces
dialog again, and inInput file
choosebrowse
. Navigate to the ISIS-Sample data and select the two files,MAR27691_red.nxs
andMAR27698_red.nxs
using shift key.Add the loaded workspaces
Click
Run
This should result in three new workspaces again, this time with file ranges as their name
In the main GUI right-click on
MAR27691-27698_graphite002_red_elwin_eq2
and choosePlot Spectrum
, choosePlot All
This should plot two lines of \(ln(Counts(microAmp.hour))^{-1}\) vs \(Q2\)
2. Indirect data¶
Go to
Interfaces
>Inelastic
>Data Manipulation
Click on
Add Workspaces
, a dialog window should promptEnter
irs26176_graphite002_red.nxs
inInput file
. The table of the dialog should be populated with theirs26176_graphite002_red
workspace.Select the workspace from the table and click on
Add Data
. Close the dialog.Back on
Elwin
tab, clickRun
- this should produce 3 new workspaces_elf
,_eq
and_eq2
Open the
Add Workspaces
dialog again, and inInput file
choosebrowse
. Navigate to the ISIS-Sample data and select the two files,irs26174_graphite002_red.nxs
andirs26176_graphite002_red.nxs
using shift key.Add the loaded workspaces
Change the integration range from -0.2 to 0.2
Click
Run
This should result in three new workspaces again, this time with file ranges as their name
In the main GUI right-click on
irs26174-26176_graphite002_red_elwin_eq2
and choosePlot Spectrum
, choosePlot All
This should plot two lines of \(ln((meV))^{-1}\) vs \(Q2\)
Right-click on the
irs26176_graphite002_elwin_eq
workspace andSave Nexus
; save to a location of your choice; you will use this file in the next test
I(Q, T) tab¶
Time required 3 - 5 minutes for each
1. Direct data¶
Go to
Interfaces
>Inelastic
>Data Manipulation
Go to the
Iqt
tabLoad the
MARI27691_sqw.nxs
file from the sample dataLoad the resolution file
MARI27698_sqw.nxs
from the sample dataClick
Run
A new workspace with the suffix
_iqt
should appear in the main GUI, it should be a workspace with 17 histograms and 3 bins.Click
Plot Current preview
this should plot the same data as the preview windowChoose some workspace indices (e.g. 0-2) in the
Output
section and clickPlot Spectra
this should give a plot with the title MARI27691_iqtClick the down arrow on the
Plot Spectra
button and then selectPlot Tiled
. This should give a tiled plot of the selected workspace indices.
2. Indirect data¶
Go to
Interfaces
>Inelastic
>Data Manipulation
Go to the
Iqt
tabLoad the
irs26176_graphite002_red.nxs
file from the sample dataLoad the resolution file
irs26173_graphite002_res.nxs
from the sample dataClick
Run
A new workspace with the suffix
_iqt
should appear in the main GUI, it should be a workspace with 51 histograms and 86 bins. NB keep this workspace for the next testClick
Plot Current preview
this should plot the same data as the preview windowChoose some workspace indices (e.g. 0-2) in the
Output
section and clickPlot Spectra
this should give a plot with the title irs26176_graphite002_iqtClick the down arrow on the
Plot Spectra
button and then selectPlot Tiled
. This should give a tiled plot of the selected workspace indices.
