Find the frequency range in which peaks are coming in FFT

Hi all,

I've FFT plot for a signal. I want to find the frequency ranges in which the peaks are coming.

For example, in this case, I've marked 6 frequency ranges.

How do I get that??? I really need your help as I'm new to Matlab and signal processing.

I'm attached sample time domain data also. [ts=.5*10^-6; Fs=1/ts;]

doc findpeaks

if you have the Signal Processing Toolbox. It has various parameters that you would have to play around with. How you are defining the regions around a peak I don't know though. You'll have to find a way to put that into a condition you can test for.
