[FieldTrip] Best procedure for frontal alpha asymmetry

[Harsimrat Singh]

Dear Fieldtrippers

I am trying to calculate the difference in the alpha power on the
frontal electrodes for a subject wise analysis.

Can someone please suggest what will be the correct approach.

Run freq analysis with alpha freq (14-18 ) with a resolution of 2Hz on
all channels and then do

tf.powspctrm (:,left,:,:) –tf.powsprctrm(:,right,:,:)

OR

run freq analysis on left chans and right chans separately and then do
subtraction.

Best regards
Harsimrat
