Move PeakRadius properties from PeaksWorkspace to peaks

[Vickie Lynch]

This ticket will be the first stop toward arbitrary integration shapes for integrated peaks in Q space. Each peak should have a PeakRadius, BackgroundInnerRadius, and BackgroundOuterRadius that is used for plotting in the SliceViewer. Test with AdaptiveQRadius checked in IntegratePeaksMD.

[Vickie Lynch]

To test:
Load(Filename='TOPAZ_6674_event.nxs',OutputWorkspace='TOPAZ_6674_event',FilterByTofMin='2000',FilterByTofMax='16500',LoadMonitors='1',MonitorsAsEvents='1')
ConvertToDiffractionMDWorkspace(InputWorkspace='TOPAZ_6674_event',OutputWorkspace='TOPAZ_6674_MD',OutputDimensions='Q (sample frame)',SplitThreshold='50',MaxRecursionDepth='11')
FindPeaksMD(InputWorkspace='TOPAZ_6674_MD',PeakDistanceThreshold='0.47099999999999997',MaxPeaks='100',OutputWorkspace='peaks_ws')
CentroidPeaksMD(InputWorkspace='TOPAZ_6674_MD',PeaksWorkspace='peaks_ws',OutputWorkspace='peaks_ws')
FindUBUsingFFT(PeaksWorkspace='peaks_ws',MinD='4',MaxD='12',Tolerance='0.12')
IndexPeaks(PeaksWorkspace='peaks_ws',Tolerance='0.12')
SelectCellOfType(PeaksWorkspace='peaks_ws',CellType='Rhombohedral',Centering='R')
IntegratePeaksMD(InputWorkspace='TOPAZ_6674_MD',CoordinatesToUse='Q (sample frame)',PeakRadius='0.02',PeaksWorkspace='peaks_ws',OutputWorkspace='peaks_ws_sphere_adaptive',AdaptiveQRadius='1',CylinderLength='0.40000000000000002',PercentBackground='20',ProfilesFile=r'/home/vel/mantid/Code/release/bin/new.profiles')

Radii of integration are function of magnitude of Q at peak center

[Owen Arnold]

This is a nice addition, and the implementation looks good. I've tested this out with the SliceViewer and it works okay, the only problem is that in saving (SaveNexus) and loading, these log properties are getting lost. I'm pretty sure that that didn't used to happen.

Try saving your IntegratedPeaks file and then load it as a workspace called 'temp' run something like:

run = temp.run()
val = run.getLogData('PeakRadius')

The PeakRadius has not been preserved in the save/load cycle, so the overlay turns up in the SliceViewer as position only.

[Vickie Lynch]

I saved the integrated peaks with SaveNexus and then used Load. The vector PeakRadius was read in correctly, but the QSample was identical to QLab and the circles were not over the peaks. This also happened in the nightly build without my changes. I also loaded a peaks file with only one PeakRadius. The one value is printed, but the SliceViewer has the error PeakRadius is not the requested type when I add that peaks workspace to the slice.

Load(Filename=r'/home/vel/workspace/adaptive2.nxs',OutputWorkspace='adaptive2') temp = mtdadaptive2? run = temp.run() val = run.getLogData('PeakRadius') print val.value

This looks great. I cant merge it to master because of network issues at the moment. But it's working exactly as I expect it to, including with the older file format.
