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 at least 8 columns wide into an ASCII file in 17-column Reflectometry TBL format compatible with the old ISIS Reflectometry Interface. The columns must be typed: str, str, str, str, str, str, str, int
The 8 columns are grouped into rows of 17 according to stitch index, so up to 3 rows in the table would become a single row in the TBL file like so: (Where Z is an identical stitch group index, and - is ignored as only the first instance of P and Q are used in the file)
A, B, C, D, E, P, Q, Z
F, G, H, I, J, -, -, Z
K, L, M, N, O, -, -, Z
becomes
A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q
The Algorithm will fail if any stitch index appears more than 3 times, as the old interface does not support more than 3 runs per row.
Stitch groups of index 0 are treated as non-grouped, and will not be grouped with one another (and by extension can be larger than 3 members). They will however be moved to the end of the file
Any columns after the eighth are ignored
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 LoadReflTBL
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("int","StitchGroup");
nextRow = {'Run(s)':"13460",'ThetaIn':"0.7",'TransRun(s)':"13463,13464",'Qmin':"0.01",'Qmax':"0.06",'dq/q':"0.04",'Scale':"",'StitchGroup':1}
