[Eeglablist] Calculation of frequency power centroid for a specific band

[Simon-Shlomo Poil]

Dear David,

I don't think you can calculate the dominant frequency directly in
EEGLAB. However, you can using a plugin the Neurophysiological
Biomarker Toolbox (http://www.nbtwiki.net). Unfortunately we do not
yet have a tutorial on how you calculate the dominant frequency, but
you simply use the menu Compute Biomarkers | For multiple NBT signal |
Spectral Biomarkers in the NBT menu.

That will generate a nbt_PeakFit biomarker with many different
spectral measures. One of then is CentralFrequency. Which is the
"dominant frequency" in different frequency bands, it will also tell
you the power of this frequency in CentralPower.

You can also call the function directly, it's called nbt_doPeakFit

Best regards,
Simon
