Hello, I would like to automate curve fitting with a non-linear ExpDecay2 fit using direct weighting. The corresponding datasheet already contains x data (col(6)), y data (col(7), and weighting data (col(8)). I first tried to save the “direct weighting” option in a nlfit dialog design. However, this does not seem to be possible. When loading the corresponding saved design, the option "direct weighting" is deselected again under Data Selection. Is there a way to solve this with a LabTalk script? So far, I have not found a way to select “direct weighting” with the nlbegin command using the “weight:=” variable. I would be grateful for any ideas.
