[Eeglablist] visualization of rejmanual timepoints

[Cedric Cannard]

Dear Agatha,

While I don't know about this previous feature, here is how you can 1) make a copy of your EEG dataset, 2) remove bad portions from that copy, 3) visualize the differences, and 4) remove these segments from original dataset if satisfied. 

EEG2 = EEG;                 % copy
pop_eegplot(EEG2,1,1,1);    % plot and remove bad segments manually
vis_artifacts(EEG2,EEG);    % compare (removed segments are in red)
mask = sum(abs(EEG.data-EEG2.data),1) > 1e-10;  % mask index of bad samples
badData = reshape(find(diff([false mask false])),2,[])'; % reshape for pop_select function
badData(:,2) = badData(:,2)-1; % fix latency
cleanEEG = pop_select(EEG,'nopoint',badData);  

Hope this helps,

Cedric
