CreatePeaksWorkspace dialog.
Table of Contents
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| InstrumentWorkspace | Input | Workspace | An optional input workspace containing the default instrument for peaks in this workspace. | |
| NumberOfPeaks | Input | number | 1 | Number of dummy peaks to initially create. |
| OutputWorkspace | Output | IPeaksWorkspace | Mandatory | An output workspace. |
| OutputType | Input | string | Peak | Output peak workspace type, default to full peak workspace. Allowed values: [‘Peak’, ‘LeanElasticPeak’] |
This algorithm can be used to create a:
Use LoadIsawPeaks v1 or FindPeaksMD v1 to create a peaks workspace with peaks.
This workspace can serve as a starting point for modifying the PeaksWorkspace, using the GUI or python scripting, for example.
If the input workspace is a MDWorkspace then the instrument from the first experiment info is used.
Example: An empty table, not tied to an instrument
ws = CreatePeaksWorkspace()
print("Created a {} with {} rows".format(ws.id(), ws.rowCount()))
Output:
Created a PeaksWorkspace with 0 rows
Example: Create an empty LeanElasticPeaksWorkspace, not tied to an instrument
ws = CreatePeaksWorkspace(NumberOfPeaks=0, OutputType="LeanElasticPeak")
print("Created a {} with {} rows".format(ws.id(), ws.rowCount()))
Output:
Created a LeanElasticPeaksWorkspace with 0 rows
Example: With a few peaks in place
sampleWs = CreateSampleWorkspace()
ws = CreatePeaksWorkspace(InstrumentWorkspace=sampleWs,NumberOfPeaks=3)
print("Created a {} with {} rows".format(ws.id(), ws.rowCount()))
Output:
Created a PeaksWorkspace with 3 rows
