Hello Tiago,

thank you for your response.
I didn't realize you could also do a Plot Profile of a specified line. This looks very helpful.
I tried working with the fitting tool and it works ok as long as the Plot Profile of my image contains only a single peak.
What I'm trying to do is write a program (or Makro) which does a Plot Profile of the whole image and fits each peak that occurs.
What I can also imagine is isolating the regions which form the peaks and then fitting them individually.
For example this part would form the big peak of my Plot Profile of the entire image.



But for now, I only know how to do that manually (as in putting a region of interest around them by hand and doing a Plot Profile of that which I can then fit).
Is there a way to seperate these regions automatically? Fitting them afterwards wouldn't be a problem.
Another thing that comes to mind is multifitting as you can do in Origin for example, but ImageJ doesn't seem to support that (at least not in the standard curve fitting tool).
