[FieldTrip] How to calculate relative power for source imaging

[Aaron Lam]

Dear Fieldtrip Community,
I am new to fieldtrip and have been using it to analyse sleep and resting wake data.
I have managed to calculate the absolute power for source imaging and successfully projected it onto individual participant’s MRI.
I wonder if there is a way to easily calculate relative power (frequency of interest / grand total power).


Kind Regards,
Aaron
