Name | Direction | Type | Default | Description |
---|---|---|---|---|
Filename | Input | string | Mandatory | The name of the NeXus file to load. Allowed extensions: [‘.nxs’] |
OutputWorkspace | Output | MatrixWorkspace | Mandatory | The name of the Workspace2D to create. |
Signal | Input | number | 1 | Number of the signal to load from the file. Default is 1 = time_of_flight. Some NXS files have multiple data fields giving binning in other units (e.g. d-spacing or momentum). Enter the right signal number for your desired field. |
SpectrumMin | Input | number | 1 | The index number of the first spectrum to read. Only used if spectrum_max is set. |
SpectrumMax | Input | number | Optional | The number of the last spectrum to read. Only used if explicitly set. |
This algorithm loads a NeXus file that conforms to the TOFRaw format and stores it in a 2D workspace. The TOFRaw format is used at SNS and consists of a histogram representation with common bin boundaries.
Some NXS files have multiple data fields giving binning in other units (e.g. d-spacing or momentum). You can choose which binning to use by entering the Signal parameter. The default value is 1, which normally will correspond to TOF. The “Y” units will still be in counts.
The typical meanings of Signal are as follows (note that these may change!):
