Description

InputWorkspace

Input

MatrixWorkspace

Mandatory

An input workspace.

MaskWorkspace

Input

MatrixWorkspace

An optional mask workspace.

OutputWorkspace

Output

MatrixWorkspace

Mandatory

An output workspace.

Description

This algorithm is useful for removing unwanted spectra using masks. If MaskWorkspace is provided it is used to select the spectra to remove. Otherwise the internal mask in the InputWorkspace is used.

Usage

Example - ExtractUnmaskedSpectra

# Create histogram workspace
ws = CreateSampleWorkspace()

# Mask 10 spectra
MaskDetectors(ws, [1,2,3,4,5,6,7,8,9,10])

# Extract unmasked into a new workspace
ows = ExtractUnmaskedSpectra(ws)

# Compare workspace sizes
print('Number of spectra in original workspace {}'.format(ws.getNumberHistograms()))
print('Number of spectra in cropped  workspace {}'.format(ows.getNumberHistograms()))

Output:

Number of spectra in original workspace 200
Number of spectra in cropped  workspace 190
