Burni,
may I remind you that ImageJ is for image processing. Although it
supplies a number of routines that are suitable for 1D-signal
processing, there are better tools available for this kind of tasks.
Furthermore I don't think that at least some of the peaks should be
fitted by a Gaussian. Is there any a priori reason for your assumption?
Best
Herbie
