Workspace produced by ConvertToYSpace creates problem for slice viewer

[Alex Buts]

Run script below and try to view the resulting workspace in sliceviewer.

Mantid is throwing unexpected exception while creating Histo dimension.

 tof_ws = CreateSimulationWorkspace(Instrument='MAR',BinParams=[-50,2,50],UnitX='TOF')
SetInstrumentParameter(tof_ws,ParameterName='t0',ParameterType='Number',Value='0.5')
SetInstrumentParameter(tof_ws,ParameterName='efixed',ParameterType='Number',Value='30.')    
###### Convert data to format acceptable by ConvertToYSpace
tof_ws = ConvertToPointData(tof_ws)
###### Convert to Y Space
wsY=ConvertToYSpace(InputWorkspace='tof_ws',Mass='30')

What are you trying to achieve here? It's quite an unusual use for this algorithm. The transform is solely used by the compton scattering area (Vesuvio) and doesn't make a lot of sense to use it on something like MARI.

[Alex Buts]

I have produced a workspace and trying to explore it. The sliceviewer option is available so I just try to invoke it.

Compton is kind of inelastic, is not it? Mary may be very inefficient in doing this but a formal image can be available.

I think, the ticket illustrate common problem in visualizing a distribution workspace by slice-viewer. As such, it is rather sliceviewer then ConvertToYSpace ticket, as I can obtain distribution workspace by different means.

Moved to the backlog at the code freeze of R3.3
