This should be a common question but I couldn’t find the answer at google in one page.

I have saved EEG data from the gtec USBamp via the BCI2000 software saving it as GDF file.

I can load up the GDF file in EEGlab in Matcad. I’m new in Matcad. Can you show a link or give me instructions how to get FFT plot using the GDF data loaded in EEGlab? There should be a generic code for this. Please share the code and I’ll learn from the code after running the FFT. It would take so long to spend months studying Matcad just to load up the GFD file from EEGLab and do the FFT plot. Thank you.
