CopyDataRange v1

Summary

Replaces a range of data in the destination workspace with a specified continuous range of data from the input workspace

Properties

Name	Direction	Type	Default	Description
InputWorkspace	Input	MatrixWorkspace	Mandatory	The workspace containing a range of data to be used for the replacement.
DestWorkspace	Input	MatrixWorkspace	Mandatory	The workspace to have range of data replaced.
StartWorkspaceIndex	Input	number	0	The index denoting the start of the spectra range.
EndWorkspaceIndex	Input	number	Optional	The index denoting the end of the spectra range.
XMin	Input	number	Optional	An X value that is equal to the lowest point to copy (point data), or an X value that is within the first bin to copy (histogram data).
XMax	Input	number	Optional	An X value that is equal to the highest point to copy (point data), or an X value that is within the last bin to copy (histogram data).
InsertionYIndex	Input	number	0	The index denoting the histogram position for the start of the data replacement in the DestWorkspace.
InsertionXIndex	Input	number	0	The index denoting the x position for the start of the data replacement in the DestWorkspace.
OutputWorkspace	Output	MatrixWorkspace	Mandatory	The name to give the output workspace.

Description

This algorithm takes a continuous block of data from an input workspace and places this data into a destination workspace, replacing the data in the destination workspace at which the insertion is specified. The block of data to be used is specified by entering spectra indices and x indices within the input workspace into the algorithm. The insertion location is then specified by an InsertionYIndex and InsertionXIndex within the destination workspace.

Note that this algorithm will replace not only the Y values, but also the E values within the destination workspace. The original input workspace remains unchanged.

Usage

Example - Copy Data Range within one workspace over to another

# Create two workspaces
demo_ws1 = CreateWorkspace(DataX=[1,2,3], DataY=[1,2,3], DataE=[1,1,1], NSpec=1)
demo_ws2 = CreateWorkspace(DataX=[1,2,3], DataY=[4,5,6], DataE=[2,2,2], NSpec=1)

# Copy some of the data from the input workspace over to the destination workspace
output = CopyDataRange(InputWorkspace=demo_ws1, DestWorkspace=demo_ws2, StartWorkspaceIndex=0, EndWorkspaceIndex=0,
                       XMin=1, XMax=2, InsertionYIndex=0, InsertionXIndex=0)

# Display the output workpace data
print("Output x data: {0}".format(output.readX(0)))
print("Output y data: {0}".format(output.readY(0)))
print("Output e data: {0}".format(output.readE(0)))

Output:

Output x data: [ 1.  2.  3.]
Output y data: [ 1.  2.  6.]
Output e data: [ 1.  1.  2.]
