SliceViewer: read XML from multislice to open the slice viewer at a particular point

[Janik Zikovsky]

Interpret the XML to open the slice viewer on the same slice being viewed in the VATES simple gui.

[Michael Reuter]

OK, here is the XML that will be generated by the slice from the simple interface:

<MDInstruction><MDWorkspaceName>TOPAZ_3680</MDWorkspaceName><DimensionSet><Dimension ID="Q_lab_x"><Name>Q_lab_x</Name><Units>Angstroms^-1</Units><UpperBounds>15.0000</UpperBounds><LowerBounds>-15.0000</LowerBounds><NumberOfBins>10</NumberOfBins></Dimension><Dimension ID="Q_lab_y"><Name>Q_lab_y</Name><Units>Angstroms^-1</Units><UpperBounds>15.0000</UpperBounds><LowerBounds>-15.0000</LowerBounds><NumberOfBins>10</NumberOfBins></Dimension><Dimension ID="Q_lab_z"><Name>Q_lab_z</Name><Units>Angstroms^-1</Units><UpperBounds>15.0000</UpperBounds><LowerBounds>0.0000</LowerBounds><NumberOfBins>10</NumberOfBins></Dimension><XDimension><RefDimensionId>Q_lab_x</RefDimensionId></XDimension><YDimension><RefDimensionId>Q_lab_y</RefDimensionId></YDimension><ZDimension><RefDimensionId>Q_lab_z</RefDimensionId></ZDimension><TDimension><RefDimensionId/></TDimension></DimensionSet><Function><Type>PlaneImplicitFuction</Type><ParameterList><Parameter><Type>NormalParameter</Type><Value>1 0 0</Value></Parameter><Parameter><Type>OriginParameter</Type><Value>4.84211 0 0</Value></Parameter></ParameterList></Function></MDInstruction>

[Janik Zikovsky]

Can you give me an example of XML that would come if someone where viewing a slice in a 4D workspace?

[Michael Reuter]

Here is a 4D XML:

<MDInstruction><MDWorkspaceName>fe_demo_sqw</MDWorkspaceName><DimensionSet><Dimension ID="Q_\zeta"><Name>Q_\zeta</Name><Units>Ang</Units><UpperBounds>5.7415</UpperBounds><LowerBounds>-1.5197</LowerBounds><NumberOfBins>10</NumberOfBins></Dimension><Dimension ID="Q_\xi"><Name>Q_\xi</Name><Units>Ang</Units><UpperBounds>6.7070</UpperBounds><LowerBounds>-6.6071</LowerBounds><NumberOfBins>10</NumberOfBins></Dimension><Dimension ID="Q_\eta"><Name>Q_\eta</Name><Units>Ang</Units><UpperBounds>6.6071</UpperBounds><LowerBounds>-6.6071</LowerBounds><NumberOfBins>10</NumberOfBins></Dimension><Dimension ID="E"><Name>E</Name><Units>MeV</Units><UpperBounds>150.0000</UpperBounds><LowerBounds>0.0000</LowerBounds><NumberOfBins>10</NumberOfBins></Dimension><XDimension><RefDimensionId>Q_\zeta</RefDimensionId></XDimension><YDimension><RefDimensionId>Q_\xi</RefDimensionId></YDimension><ZDimension><RefDimensionId>Q_\eta</RefDimensionId></ZDimension><TDimension><RefDimensionId>E</RefDimensionId></TDimension></DimensionSet><Function><Type>PlaneImplicitFuction</Type><ParameterList><Parameter><Type>NormalParameter</Type><Value>1 0 0</Value></Parameter><Parameter><Type>OriginParameter</Type><Value>3.98234 0 0</Value></Parameter></ParameterList></Function></MDInstruction>

[Janik Zikovsky]

Thank you - but I think it is missing the information of what is the current "Time" value for the 4th dimension (Energy in this example).

[Michael Reuter]

Yes, that is an important piece of information. However, the current XML schema doesn't support it and I'm not sure where to place that type of information. That's why I'm including Owen on this ticket. What we could do in the meantime is have an optional argument in the function that takes the XML for a time parameter. 4D datasets could pass their initial time that way. We'd also need a mechanism for updating the SliceViewers when the animation controls are used. Alternatively, we can make the user open a new instance.

[Owen Arnold]

How about adding an extra element to <TDimension>? Something like <Value></Value>, so the current xml would change from <TDimension><RefDimensionId>E</RefDimensionId></TDimension> to <TDimension><RefDimensionId>E</RefDimensionId><Value>10.1</Value><TDimension>

Just make sure that the Schema in the Vates ADD is kept up to date. Alas, Poco xml isn't sophisticated enough to understand or work with schemas, so all the xml processing is manual. I think everything else should just work. In any case, the exising functionality is heavily unit-tested/gui-tested so you should easily identify anything that breaks as a result of this change.

[Michael Reuter]

OK, here is the XML for a 4D dataset with the timestep value inserted:

<MDInstruction><MDWorkspaceName>fe_demo_sqw</MDWorkspaceName><DimensionSet><Dimension ID="Q_\zeta"><Name>Q_\zeta</Name><Units>Ang</Units><UpperBounds>5.7415</UpperBounds><LowerBounds>-1.5197</LowerBounds><NumberOfBins>10</NumberOfBins></Dimension><Dimension ID="Q_\xi"><Name>Q_\xi</Name><Units>Ang</Units><UpperBounds>6.7070</UpperBounds><LowerBounds>-6.6071</LowerBounds><NumberOfBins>10</NumberOfBins></Dimension><Dimension ID="Q_\eta"><Name>Q_\eta</Name><Units>Ang</Units><UpperBounds>6.6071</UpperBounds><LowerBounds>-6.6071</LowerBounds><NumberOfBins>10</NumberOfBins></Dimension><Dimension ID="E"><Name>E</Name><Units>MeV</Units><UpperBounds>150.0000</UpperBounds><LowerBounds>0.0000</LowerBounds><NumberOfBins>10</NumberOfBins></Dimension><XDimension><RefDimensionId>Q_\zeta</RefDimensionId></XDimension><YDimension><RefDimensionId>Q_\xi</RefDimensionId></YDimension><ZDimension><RefDimensionId>Q_\eta</RefDimensionId></ZDimension><TDimension><RefDimensionId>E</RefDimensionId><Value>60</Value></TDimension></DimensionSet><Function><Type>PlaneImplicitFuction</Type><ParameterList><Parameter><Type>NormalParameter</Type><Value>1 0 0</Value></Parameter><Parameter><Type>OriginParameter</Type><Value>3.90749 0 0</Value></Parameter></ParameterList></Function></MDInstruction>

When a rebinner is used from within the simple interface via MantidPlot, the output workspace name is now: __wsName_mdhisto where wsName is that given in the XML.

Looks like it works well on the original workspace at least. Not yet tested on rebinned version (i'm not yet looking for the rebinned name)

Works nicely off the right-click menu on each slider.

Numeric value for slice position reported accurately.
