Statistics from spectrogram

Hello,

I'm a new matlab user working with the student version. I'm working on a project where I analyze short ultrasonic calls produced by mice. I've been viewing the calls with a spectrogram, and am trying to determine a few statistics from them. I would like to know the frequency that each call starts and ends at, the maximum and minimum frequency of each call, and the frequency of the maximum amplitude. Is there a way to calculate these frequencies without viewing the spectrogram?

Thank you for your time and attention.

-Alan

When you use the SPECTROGRAM command in the following way, no MATLAB figure is created:

T = 0:0.001:2;
X = chirp(T,100,1,200,'q');
[S,F,T,P]=spectrogram(X,128,120,128,1E3);
