Greetings,
I made a thread some days ago about finding peaks in a plot profile.
What I want to do now is use these peaks as an estimation for the parameters of a Gaussian Fit.
I will be working with a Profile like this:
With the help of the people in the old thread, I can now find the positions of the absolute peaks very reliably.
The problem I have now is the fact that ImageJ does not seem to support multi-fitting.
Even when I tried the fitting tool for 'User-defined functions', it only allows 6 parameters. But for a multi-gauss fit with 2 peaks, I would already need 7.
Does anybody perhaps know of an addon that supports more options for fitting? Specifically a gaussian multi-fit would help me greatly.
