Hi Raymundo. Thank you very much for the help. I've implemented some code that Francois uploaded (Fitting oscillations and one-over-F (FOOOF) enquiry - #4 by Francois), but unfortunately, it gives me the highest frequency band with a resolution of 1 Hz. In the papers, they report those values with a 0.125 Hz resolution (e.g., https://doi.org/10.1016/j.cub.2014.11.034). Do you know how can this be fixed in Brainstorm? I've tried both with the FFT and pwelch methods, and both gave me highest frequencies with 1 Hz precision.
