ConvertToMatrixWorkspace v1

Summary

Converts an EventWorkspace into a Workspace2D, using the input workspace’s current X bin values.

ConvertToEventWorkspace, Rebin

Properties

Name	Direction	Type	Default	Description
InputWorkspace	Input	MatrixWorkspace	Mandatory	An input EventWorkspace.
OutputWorkspace	Output	MatrixWorkspace	Mandatory	An output Workspace2D.

Description

This can also be performed using the Rebin v1 algorithm and having the “PreserveEvents” parameter set to false.

Example - Simple conversion of an EventWorkspace

event_ws = Load('CNCS_7860_event.nxs')
# Run the conversion algorithm
histo_ws = ConvertToMatrixWorkspace(event_ws)
# Check that the original workspace and the converted workspace have the same shape
print("{} {}".format(event_ws.getNumberHistograms(), event_ws.blocksize()))
print("{} {}".format(histo_ws.getNumberHistograms(), histo_ws.blocksize()))

51200 500
51200 500

Example - Conversion when blocksize > 1

event_ws = Load('CNCS_7860_event.nxs')
# Rebin the loaded EventWorkspace to a new EventWorkspace that has > 1 bins
event_ws_rebinned = Rebin(InputWorkspace=event_ws, Params=1e3, PreserveEvents=True)
# Run the conversion algorithm
histo_ws_rebinned = ConvertToMatrixWorkspace(event_ws_rebinned)
# Check that the original workspace and the converted workspace have the same shape
print("{} {}".format(event_ws_rebinned.getNumberHistograms(), event_ws_rebinned.blocksize()))
print("{} {}".format(histo_ws_rebinned.getNumberHistograms(), histo_ws_rebinned.blocksize()))

Output:

51200 17
51200 17
