[Eeglablist] get a global field power for multiple datasets

Dear all

I was wondering if there’s a way to select the time windows of interest using a global measure of components based on Global Field Power (GFP)?
I found that the following code can only calculate individual GFP. I wonder if I can get the GFP for a group of datasets (say 24 subjects)?

if length(size(EEG.data))==3
    gfp = std(mean(EEG.data,3));
end

figure;
plot(EEG.times, mean(EEG.data,3), 'k');
hold on;
plot(EEG.times, std(mean(EEG.data,3)), 'r', 'linewidth', 3);

Thank you in advance!
