Hi Francois. Is it possible to extract the psd value according to each brain regions?
I have averaged my data according to group and want to extract the psd value for all brainwaves and brain regions according to AAL3 atlas.

save333
I got all the psd for each brainwaves, but not for the brain regions. I am not sure where all the 30022 is coming from. TQ for ur help.
