This is a Python binding to the C++ class Mantid::API::IMDWorkspace.

bases: mantid.api.Workspace, mantid.api.MDGeometry

class mantid.api.IMDWorkspace

clearOriginalWorkspaces((MDGeometry)self) → None :

clone(InputWorkspace)

Copies an existing workspace into a new one.

Property descriptions:

InputWorkspace(Input:req) Workspace Name of the input workspace. Must be a MatrixWorkspace (2D or EventWorkspace), a PeaksWorkspace or a MDEventWorkspace.

OutputWorkspace(Output:req) Workspace Name of the newly created cloned workspace.

convertUnits(InputWorkspace, Target, EMode=None, EFixed=None, AlignBins=None, ConvertFromPointData=None)

Performs a unit change on the X values of a workspace

Property descriptions:

InputWorkspace(Input:req) MatrixWorkspace Name of the input workspace

OutputWorkspace(Output:req) MatrixWorkspace Name of the output workspace, can be the same as the input

Target(Input:req) string The name of the units to convert to (must be one of those registered in the Unit Factory)[DeltaE, DeltaE_inFrequency, DeltaE_inWavenumber, dSpacing, dSpacingPerpendicular, Energy, Energy_inWavenumber, Momentum, MomentumTransfer, QSquared, SpinEchoLength, SpinEchoTime, TOF, Wavelength]

EMode(Input) string The energy mode (default: elastic)[Elastic, Direct, Indirect]

EFixed(Input) number Value of fixed energy in meV : EI (EMode=’Direct’) or EF (EMode=’Indirect’) . Must be set if the target unit requires it (e.g. DeltaE)

AlignBins(Input) boolean If true (default is false), rebins after conversion to ensure that all spectra in the output workspace have identical bin boundaries. This option is not recommended (see http://docs.mantidproject.org/algorithms/ConvertUnits).

ConvertFromPointData(Input) boolean When checked, if the Input Workspace contains Points the algorithm ConvertToHistogram will be run to convert the Points to Bins. The Output Workspace will contains Bins.
