Hello,
my name is Eidan and I have an error in the Specify 1st level - hemodynamic basis function.
Every time I select on of them I got this error:

Reference to non-existent field 'cutoff'.
Error in spm_fnirs_specify1st_ui (line 215)
Hstr = sprintf('Cutoff: %d {s}',P.K.H.cutoff);
Error in spm_fnirs>push_specify_Callback (line 75)
spm_fnirs_specify1st_ui;
Error in gui_mainfcn (line 95)
feval(varargin{:});
Error in spm_fnirs (line 25)
gui_mainfcn(gui_State, varargin{:});
Error in
@(hObject,eventdata)spm_fnirs('push_specify_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating UIControl Callback
anyone know what to do in this situation?
hope you guys can help.
Eidan.

Dear Sungho,

Thanks for your useful toolbox.

I have tried to use your sample_fnirs data and follow the tutorials step for spm-fnirs.
While trying to do "Specify 1st Level", after selecting "multiple_conditions" I faced this error:

---------------------------------------------------------
Specify GLM-fNIRS for the 1st level analysis...
---------------------------------------------------------
Hemoglobin signal to be analysed: HbO

Specify experimental design...
Completed.
Specify other regressors...
Error using uicontrol
While setting the 'Max' property of UIControl:
Value must be numeric or logical.
Error in spm_input (line 1286)
h = uicontrol(Finter,'Style','Pushbutton',...
Error in spm_fnirs_specify1st_ui (line 150)
spm_input('Other regressors (eg, systemic confounds)',1,'d');
Error in spm_fnirs>push_specify_Callback (line 75)
function push_specify_Callback(hObject, eventdata, handles)
Error in gui_mainfcn (line 95)
feval(varargin{:});
Error in spm_fnirs (line 25)
gui_mainfcn(gui_State, varargin{:});
Error in

I have checked that only the path for "spm12" exists in my MATLAB.
I would appreciate if you help me to find the problem.

Thanks for your time.

Dear Sungho,

Thanks for your quick response.
I have tried the updates codes that you gave me but still, have the same problem after trying to upload "multiple_conditions.mat" file.
Also, I tried to follow the steps for entering the experimental design instead of using "multiple_conditions.mat" and I got this error:

--------------------------------------------------------
Specify GLM-fNIRS for the 1st level analysis...
---------------------------------------------------------
Hemoglobin signal to be analysed: HbOHbR

Specify experimental design...

Your help would be really appreciated.
