Dear community,

I failed to view scalp connectivity of 19 channel EEG electrodes as I encountered the following error:

.....................
Attempted to access surf.sphere(:,5); index out of bounds because size(surf.sphere)=[1,4].

Error in BrainNet_Option>Initialization (line 327)
if EC.lbl_threshold>max(surf.sphere(:,5))||EC.lbl_threshold
Error in BrainNet_Option_BrainNet_Option_OpeningFcn (line 79)
Initialization(handles);
Error in gui_mainfcn (line 220)
feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});
Error in BrainNet_Option (line 52)
[varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
Error in BrainNet>NV_m_LF_Callback (line 3634)

I appreciate your suggestions to sort it out.

Thank you.
