Hello,

this is my first post in this forum and I'm not very experienced with ImageJ.
I've been looking for help with a particular problem where I'll probably be using the Plot Profile of an image.
The following is an example of the raw image I'll be using:



This one is basicly the same, but I adjusted the contrast a little so you can better see what's happening.



When I generate the Plot Profile of that image using control+alt+k (I specifically need this one, not the one using control+k), I get this:



What I'm finally looking for is a way to reliably find the positions (or more specifically the x-coordinates) of these peaks in whatever Plot Profile I generate. There is a different number and height of peaks depending on each picture.



My first guess was to use the fitting tool of ImageJ, but it seems to be too limited to use it for this task.
I'm not even sure if fitting would be necessary at all.
I would be very thankful for any suggestions on how to go about this problem.
I uploaded the raw image below.

Thanks in advance to anyone, who might help me.
