SaveCSV dialog.
Table of Contents
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| InputWorkspace | Input | MatrixWorkspace | Mandatory | The filename of the output CSV file |
| Filename | Input | string | Mandatory | The name of the workspace containing the data you want to save to a CSV file. Allowed extensions: [‘.csv’] |
| Separator | Input | string | , | The separator that will go between the numbers on a line in the output file (default ‘,’) |
| LineSeparator | Input | string | \n | The string to place at the end of lines (default new line character) |
| SaveXerrors | Input | boolean | False | This option saves out the x errors if any are present. If you have x errors in your workspace and you do not select this option, then the x errors are not saved to the file. |
The format of the saved ascii CSV file for a 1D worksspace consists of three columns where the numbers of each row are seperated by the Separator and each line by the LineSeparator.
The format of the saved CSV file for a 2D workspace is as follows:
A 0, 200, 400, 600, ..., 50000
0 10, 4, 234, 35, ..., 32
1 4, 234, 4, 9, ..., 12
A 0, 100, 200, 300, ..., 25000
2 34, 0, 0, 0, ..., 23
ERRORS
0 0.1, 3.4, 2.4, 3.5, ..., 2
1 3.1, 3.3, 2.5, 3.5, ..., 2
2 1.1, 3.3, 2.4, 5, ..., 2.4
where for the matrix above the ERRORS line the first column shows the content of the numbers on the of the same line; i.e. ‘A’ is followed by x-axis values (e.g. TOF values) and any number (e.g. ‘2’) followed by y-axis values (e.g. neutron counts). Multiple ‘A’ may be present to allow for the a-axis to change. So in the example above the saved 2D workspace consists of three histograms (y-axes) where the first two have the same x-axis but the third histogram has a different x-axis.
The matrix following the ERRORS line lists the errors as recorded for each histogram.
import os
# Create a file path in the user home directory
filePath = os.path.expanduser('~/SavedCSVFile.csv')
# Create a workspace
ws=CreateSampleWorkspace()
# Save it in Nexus format
SaveCSV(ws,filePath)
