How to calculate the FFT of a signal that is generated in SIMULiNK?

Hello! I have to get the frequencies present in a signal. This signal has been generated in a scope (in SIMULINK) whose data has been saved as "ScopeData7_Te". I tried using the FFT analysis tool in the "powergui" but am not satisfied. Basically, I just want the frequencies present in this signal. The data saved is a "Structure with time". Can I import this data in MATLAB and then perform a frequency analysis? If yes, how do I do that?
