I'm a researcher, and trying to fit my DNA's force-extension data from magnetic tweezers to worm-like chain model. Although I defined the equation correct and it gives me correct curve at the end, during the fitting it says 'Fit did not converge-reason unknown' and at the end in the report sheet Fit status is displayed as 'Failed(-207)'. I would like to use the Rsquare value to understand how the fitting is well, but because the fitting fails, it is very low. So, What should I be doing? There is no problem in the raw data, but I think I'm missing something.
It is not always possible to diagnose such things here unfortunately. If you are willing, please send us your project and the FDF file (from the `fitfunc` sub-folder of your User Files folder) and we'll take a look.
Thanks, Chris Drozdowski Originlab Technical Support
