[Eeglablist] Question - EEGLAB calculating GFP vs FFT

Dear all,

I am a junior neuromarketing researcher and am new to the EEGLAB program. I
have 14 EEG recordings of 2-minute participant exposure to advertisement. I
have segmented each data-set into 'epochs of interest'.

I wish to ask how I can determine the total *average* GFP theta z-score and
GFP alpha z-scores similar to the paper below. And further, can EEGLAB
produce graphs as shown in the paper?

Also, how different are GFP and FFT analyses? From what I can understand,
they yield similar results.

Working Memory, Emotion, and Imagination in Narrative Transportation. *

I would really appreciate any and all help!

Thank you in advance.
