Description

InputWorkspace

Input

MatrixWorkspace

Optional: An input workspace with the instrument we want to use.

InstrumentName

Input

string

Optional: Name of the instrument on which to base the GroupingWorkspace.

InstrumentFilename

Input

string

Optional: Path to a file (full or relative) defining the instrument on which to base the GroupingWorkspace. The file could be an IDF or a NeXus Geometry file. Note, InstrumentFilename or InstrumentName must be specified, but not both. Allowed extensions: [‘.xml’, ‘.hdf5’, ‘.nxs’, ‘.nxs.h5’]

Filename

Input

string

Mandatory

The DspacemapFile containing the d-space mapping. Allowed extensions: [‘.dat’, ‘.bin’]

FileType

Input

string

POWGEN

The type of file being read. Allowed values: [‘POWGEN’, ‘VULCAN-ASCII’, ‘VULCAN-Binary’]

OutputWorkspace

Output

OffsetsWorkspace

Mandatory

An output OffsetsWorkspace.

Description

Loads a Dspacemap file (POWGEN binary, VULCAN binary or ascii format) into an OffsetsWorkspace.

The resulting workspace can then be used with, e.g. AlignDetectors to perform calibration.

Usage

This algorithm is SNS specific in its use.

Note

To run these usage examples please first download the usage data, and add these to your path. In Mantid this is done using Manage User Directories.

ws = LoadDspacemap(InstrumentFilename="VULCAN_Definition_2006-01-31.xml", Filename="pid_offset_vulcan_new.dat",
                   FileType="VULCAN-ASCII")
print("Workspace type = {}".format(ws.id()))

Output:

Workspace type = OffsetsWorkspace
