Dear ImageJ users

I try to perform a gaussian fit froma a macro I am writing. Data is 2D. When
the width of the gaussian curve is narrow, ImageJ doFit function does not
fit the data. I can fit the data to Gaussian curve by changing simlex
initial guesses.

However, from the macro code, even though I gaved the initialGues array for
the parameters a, b, c, d. But it doesnt change anything. From the simlex
parameter dialog box, when I change the initial parameters, it works.

what is the problem with the macro Fit functions ?
I will be pleased if you share your opinions.

best regards
