[Eeglablist] pop_rejmenu, pop_epoch

[Ольга Протасенко]

Hello, Jason!
Thank you one more time for your answers.
The 3rd one is OK.

And I've tested some times the second (pop_epoch) and it generates an error:

--------------------------------------
??? Error using ==> pop_epoch at 226
pop_epoch(): empty epoch range (no epochs were found).

Error in ==> GUI_Finish3>btnokep_Callback at 103
                EEG = pop_epoch( EEG2, { 16 }, [-1 2], 'newname', 'Epoch 16', 'epochinfo', 'yes');

Error in ==> gui_mainfcn at 96
        feval(varargin{:});

Error in ==> GUI_Finish3 at 42
    gui_mainfcn(gui_State, varargin{:});

Error in ==> @(hObject,eventdata)GUI_Finish3('btnokep_Callback',hObject,eventdata,guidata(hObject))

 
??? Error while evaluating uicontrol Callback
---------------------------------------

My code is:

(for Radiobutton of this 16th epoch):

-------------------------------------------------
function ep16_Callback(hObject, eventdata, handles)

global epname epnumber EEG EEG2 newev num_events;    

        num_events = length(EEG.event);
        newev = EEG.event;
        for k = 1:(num_events-1)
           if strcmp(newev(k).type,'2') && strcmp(newev(k+1).type,'8')
              newev(k).type = '16';
           end
        end
        EEG2 = EEG;
        EEG2.event = newev;

epname = 'Epoch 16';
epnumber = 16;
------------------------------------

(for the main button):

function btnokep_Callback(hObject, eventdata, handles)
       global ALLEEG CURRENTSET EEG epname epnumber EEG2 newev num_events;   
           
        assignin('base','epname', epname);
        assignin('base','epnumber', epnumber); % проверка
        assignin('base','EEG2', EEG2);
        
        if epnumber == 16 
                EEG = pop_epoch( EEG2, { 16 }, [-1 2], 'newname', 'Epoch 16', 'epochinfo', 'yes');
        else
                EEG = pop_epoch( EEG, { epnumber }, [-1 2], 'newname', epname, 'epochinfo', 'yes');
        end
        
        [ALLEEG EEG] = eeg_store(ALLEEG, EEG, CURRENTSET);
        EEG = pop_rmbase( EEG, [-200    0]);
        [ALLEEG EEG] = eeg_store(ALLEEG, EEG, CURRENTSET)

        pop_rejmenu_for_GUI(EEG, 1);

---------------------------------------

Can you, please, find a mistake? For other types of epochs it runs ok.
