Peak frequency in BS

1

Good afternoon!
:slight_smile:
I just wanted to ask if there is any way to get the peak frequency or mean frenquency from a given EEG file, I mean:

Once an EEG file has been analyzed in frequency domain (e.g. Welch PSD) already, if it possible to get which frequency has the highest energy level?

Mean Frequency: MF Is the gravity center for band, expressed in Hz, for BroadBand measures (Alpha, Delta, Theta, etc..)

this measure could be useful for neurological development studies

Thanks in advance!

Not from the interface, but this is something you can easily do directly from the .mat files.
The tutorial Scripting explains different ways to interact with the values saved in the files of the Brainstorm database:

For the analysis of the PSD results, you can look at what offers the FOOOF model: https://neuroimage.usc.edu/brainstorm/Tutorials/Fooof

Thank you! I will try it!
