ExtractSingleSpectrum dialog.

Summary

Extracts the specified spectrum from a workspace and places it in a new single-spectrum workspace.

Properties

Name Direction Type Default Description
InputWorkspace Input MatrixWorkspace Mandatory The name of the input workspace.
OutputWorkspace Output MatrixWorkspace Mandatory The name under which to store the output workspace.
WorkspaceIndex Input number Mandatory The workspace index number of the spectrum to extract.

Description

Extracts a single spectrum from a Workspace2D and stores it in a new workspace.

Usage

Example

ws = CreateSampleWorkspace()
print "Workspace %s contains %i spectra" % (ws, ws.getNumberHistograms())
print "Counts for every 10th bin for workspace index 5"
print ws.readY(5)[0:100:10]

wsOut = ExtractSingleSpectrum(ws,WorkspaceIndex=5)
print "After extracting one spectra at workspace index 5"

print "Workspace %s contains %i spectra" % (wsOut, wsOut.getNumberHistograms())
print "Counts for every 10th bin for workspace index 0 (now it's 0 as wsOut only contains 1 spectra)"
print wsOut.readY(0)[0:100:10]

Output:

Workspace ws contains 200 spectra
Counts for every 10th bin for workspace index 5
[  0.3   0.3   0.3   0.3   0.3  10.3   0.3   0.3   0.3   0.3]
After extracting one spectra at workspace index 5
Workspace wsOut contains 1 spectra
Counts for every 10th bin for workspace index 0 (now it's 0 as wsOut only contains 1 spectra)
[  0.3   0.3   0.3   0.3   0.3  10.3   0.3   0.3   0.3   0.3]
