InvertMDDim inverts the dimensions of a MDHistoWorkspace. It copies the data around to match the new dimensions. This algorithm is useful when dealing with storage order issues.
Example - Inverting the axes of a MD Histo Workspace
def outputMDDimensions(ws):
num_dims = ws.getNumDims()
print "Name Bins Min Max"
for dim_index in range(num_dims):
dim = ws.getDimension(dim_index)
print "%s %i %.2f %.2f" % (dim.getName(),
dim.getNBins(), dim.getMinimum(), dim.getMaximum())
#create a test MD event workspace
mdew = CreateMDWorkspace(Dimensions=3, Extents=[-1,1,-5,5,-9,10],
Names='A, B, C', Units='U, U, U')
FakeMDEventData(mdew, PeakParams=[100000, 0, 0, 0, 1])
#convert to a MDHisto workspace suing BinMD
wsHisto = BinMD(mdew,AlignedDim0='A,-1,1,9',
AlignedDim1='B,-5,5,5',
AlignedDim2='C,-9,10,9')
print "The original workspace"
outputMDDimensions(wsHisto)
wsInverted = InvertMDDim(wsHisto)
print "\nInvertMDDim reverses the order of the dimensions"
outputMDDimensions(wsInverted)
The original workspace
Name Bins Min Max
A 9 -1.00 1.00
B 5 -5.00 5.00
C 9 -9.00 10.00
