ConvertPeaksWorkspace v1¶

Summary ¶

Bi-directional conversion between a regular PeaksWorkspace (with instrument) and a LeanElasticPeaksWorkspace (without instrument).

Properties ¶

Name	Direction	Type	Default	Description
PeakWorkspace	Input	IPeaksWorkspace	Mandatory	Workspace of Indexed Peaks
InstrumentWorkspace	Input	Workspace		Donor Workspace with instrument for conversion
OutputWorkspace	Output	IPeaksWorkspace	Mandatory	Converted Workspaces

Description ¶

This algorithm provides bi-directional conversion between regular PeaksWorkspace and LeanElasticPeaksWorkspace.

When casting a PeaksWorkspace into a LeanElasticPeaksWorkspace, information related to detector (DetID, BankName, Row, Col) is discarded. However, other experiment information are retained in the LeanElasticPeaksWorkspace, including run, hkl, goniometer, sample, as well as the corresponding information at the individual Peak level.

When casting a LeanElasticPeaksWorkspace into a PeaksWorkspace, a donor PeaksWorkspace with proper instrument configuration is required. Incorrect goniometer setting will lead to a Peak with negative wavelength, which will be excluded from the output PeaksWorkspace.

Usage ¶

PeaksWorkspace to LeanElasticPeaksWorkspace

# pws is a regular PeaksWorkspace available in memroy
ConvertPeaksWorkspace(PeakWorkspace='pws', OutputWorkspace='lpws')

LeanElasticPeaksWorkspace to PeaksWorkspace

ConvertPeaksWorkspace(
    PeakWorkspace='lpws',            # a LeanElasticPeaksWorkspace in memory
    InstrumentWorkpace="donor_pws",  # a PeaksWorkspace with correct Goniometer setting and other exp info
    OutputWorkspace='pws',           # output
    )
