I am working on an EEG emotion processing project using MATLAB and EEGLAB. My goal is to extract time-domain, frequency-domain, and wavelet-domain features from EEG data. While I have successfully extracted features from segmented data, I am facing issues when applying the pmtm function to compute the Power Spectral Density (PSD) on non-segmented data.

I have data stored in ALLEEG structure (EEGLAB). I saw the following code (below) on how to display Matlab FFT plot in https://github.com/PTDZ/EEGLAB-FFT
