[Eeglablist] Extract epochs

[aarjona at us.es]

Hello.

I´d like to extract epochs with eeglab, but no all epochs only some of them. Nevertheless, I only can extract all epochs of the record using tools-extract epochs. I have done one script, but it doesn´t work:

for i=1:length(EEG.event)-1
     
    if (EEG.event(i).type==40 & EEG.event(i+1).type==44 & EEG.event(i+2).type==4)
        EEG.event(i).type=4044;    % cond. Val.Der
    end;
    if (EEG.event(i).type==20 & EEG.event(i+1).type==22 & EEG.event(i+2).type==2)
        EEG.event(i).type=2022;   % cond. Val.Izq
    end;
    if (EEG.event(i).type==40 & EEG.event(i+1).type==22 & EEG.event(i+2).type==2) 
        EEG.event(i).type=4022;   % cond. Inval.Der
    end;
    if (EEG.event(i).type==20 & EEG.event(i+1).type==44 & EEG.event(i+2).type==4)
       EEG.event(i).type=2044;   % cond. Inval.Izq
    end;
end;

EEG = pop_epoch( EEG, {'4044' '2022' '4022' '2044'}, [-0.2           2], 'newname', 'EEProbe continuous data epochs', 'epochinfo', 'yes');

Thank you very much everyone
