Error in convert to anatomical ROIs

[Sumire0612]

Dear Dr.Miyakoshi

Nice to meet you, my name is Kamiya from Osaka University School of Medicine. Thank you very much for sharing your Group SIFT with everyone. I would like to use Group SIFT toolbox to analyse ERP data.

Could you kindly teach me how to deal with the following errors?
When trying to run Determine critical values to threshold graph edges > 3. convert to anatomical ROIs in Group SIFT, I have the bug saying Function or variable 'numberOfSessiondipoles' is not recognized.

Function or variable 'numberOfSessiondipoles' is not recognized.

error: pop_groupSIFT_convertToGroupAnatomicalRois>minSubjPercentTestPushbutton_Callback (Line 864)
for m = 1:numberOfSessiondipoles

error: gui_mainfcn (Line 95)
feval(varargin{:});

error: pop_groupSIFT_convertToGroupAnatomicalRois (Line 70)
gui_mainfcn(gui_State, varargin{:});

error:
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)pop_groupSIFT_convertToGroupAnatomicalRois('minSubjPercentTestPushbutton_Callback',hObject,eventdata,guidata(hObject))

Environment: Matlab: R2023b, EEGlab: ver2023.1, Group SIFT: ver0.31
ERP data: EDF file of 19ch, Using EEGlab for preprocessing（e.g. band-pass, resampling, ICA）

Please let me know the solution to this problem.

Sincerely
