Summary

Transpose the dimensions of a MDWorkspace to create a new output MDWorkspace

Alias

This algorithm is also known as: PermuteMD

Properties

Name Direction Type Default Description
InputWorkspace Input IMDHistoWorkspace Mandatory An input workspace.
Axes Input int list   Permutes the axes according to the indexes given. Zero based indexing. Defaults to no transpose.
OutputWorkspace Output IMDHistoWorkspace Mandatory An output workspace.

Description

Performs an axis-aligned traspose of a MDHistoWorkspace. Default Axes setting gives not transpose. It is possible to remove dimensions from the input workspace by omitting those dimension indexes from the Axes property. Axes are zero-based indexes.

Usage

Example - TransposeMD

def print_dims(ws):
    for i in range(ws.getNumDims()):
        print 'Dimension %i is %s' % (i, ws.getDimension(i).name)

mdws = CreateMDWorkspace(Dimensions=3, Extents='-10,10,-10,10,-10,10', Names='A,B,C',          Units='U,U,U')
FakeMDEventData(InputWorkspace=mdws, PeakParams='500000,0,0,0,3')
binned = BinMD(InputWorkspace=mdws, AlignedDim0='A,0,10,100',    AlignedDim1='B,-10,10,100', AlignedDim2='C,-10,10,1')
print 'Dimensions before',  binned.getNumDims()
print_dims(binned)
# Transpose the workspace
transposed = TransposeMD(binned, Axes=[1,0])
print 'Dimensions after', transposed.getNumDims()
print_dims(transposed)

Output:

Dimensions before 3
Dimension 0 is A
Dimension 1 is B
Dimension 2 is C
Dimensions after 2
Dimension 0 is B
Dimension 1 is A
