SaveTBL dialog.
Table of Contents
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| Filename | Input | string | Mandatory | The filename of the output TBL file. Allowed extensions: [‘.tbl’] |
| InputWorkspace | Input | TableWorkspace | Mandatory | The name of the workspace containing the data you want to save to a TBL file. |
Saves a TableWorkspace into an ASCII file in TBL format. All of the columns must be typed as str apart from the Group column which must be of type int.
The following TableWorkspace:
| Run | Angle | QMin | QMax | Energy | Group | Options |
|---|---|---|---|---|---|---|
| 14455 | 1.5 | 0.333 | 1.44 | 1.4 | 1 | |
| 14456 | 1.5 | 0.14 | 3.522 | 1.6 | 1 | ProcessingInstructions=”1:2” |
| 14457 | 1.5 | 0.83 | 2.44 | 1.2 | 2 |
becomes
Run,Angle,Qmin,Qmax,Energy,Group,Options
14455,1.5,0.333,1.44,1.4,1,
14456,1.5,1.4,3.522,1.6,1,ProcessingInstructions="1:2"
14457,1.5,0.83,2.44,1.2,2,
The Algorithm will fail if any of the columns is not of type ‘str’.
Example - Save a TableWorkspace in Reflectometry TBL format
#import the os path libraries for directory functions
import os
# Create a table workspace with data to save. You'd normally have the table workspace in mantid already, probably as a product of LoadTBL
ws = CreateEmptyTableWorkspace()
ws.addColumn("str","Run(s)");
ws.addColumn("str","ThetaIn");
ws.addColumn("str","TransRun(s)");
ws.addColumn("str","Qmin");
ws.addColumn("str","Qmax");
ws.addColumn("str","dq/q");
ws.addColumn("str","Scale");
ws.addColumn("str","StitchGroup");
ws.addColumn("str","Options");
nextRow = {'Run(s)':"13460",'ThetaIn':"0.7",'TransRun(s)':"13463+13464",'Qmin':"0.01",'Qmax':"0.06",'dq/q':"0.04",'Scale':"",'StitchGroup':"1",'Options':""}

#Create an absolute path by joining the proposed filename to a directory

# perform the algorithm
SaveTBL(Filename=savefile,InputWorkspace=ws)
#the file contains

print("File Exists: {}".format(os.path.exists(savefile)))
Output:
File Exists: True
