Is it possible to use a parameter file that was not created in
the particular script you want to use the parameters in. All the
documentation seems to just describe how to create parameters
and use these.
However, if I create a parameter file, say users.dat, and I have all
my data prewritten to it, how can I use this file and just substitute
in the params from it?
I've selected it in the parameter properties dialog and I can see the
data, but I can't see how to set these as the parameter set for my
LR only support text only files that are seperated by a delimiting character. All the details about your parameters are stored in a file 'filename'.prm.
If you have a data file create a new parameter of type 'file' use browse to select the existing file. If the tab;e appears correct you are ok. If not adjust the delimiter to match your file you should then see the table with the correct columns.
Adjust the start row to trim off any header.
You can now tell LR how to select the column either by number or by name.
Make sure that the last line in the data file has a newline at the end of it or LR will miss it.
