TransposeMD v1

Summary

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

See Also

Transpose3D, Transpose

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 {}'.format(binned.getNumDims()))
print_dims(binned)
# Transpose the workspace
transposed = TransposeMD(binned, Axes=[1,0])
print('Dimensions after {}'.format(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
