Hi, Dr. Schalk:
After I change the third argument in the P3 function from 11 to 8, it works well as before. Thank you very much.
I have tried to use P300 GUI to do the same job, but I can not make it work well. I have attached the note of the error after I select training data (there are three blocks in the GUI, I chose the left one) in the following paragraph.
??? Reference to non-existent field 'runbutton'.
Error in ==> P300_GUI>gettrain_Callback at 248
set(handles.runbutton, 'Enable','on');
Error in ==> gui_mainfcn at 75
feval(varargin{:});
Error in ==> P300_GUI at 41
gui_mainfcn(gui_State, varargin{:});
??? Error using ==> P300_GUI('gettrain_Callback',gcbo,[],guidata(gcbo))
Reference to non-existent field 'runbutton'.
??? Error while evaluating uicontrol Callback
I have tried to load the data file in two types: one is *.dat, the other is *.mat (I have converted the data file into m file by the BCI2ASCII tool). The same note of error appeared.
There are also many arguments needed to fill in in the GUI, which make me very confused. I think a help file may be needed.
