Hello,

I'm having a problem with the temporal processing function. 
After choosing the NIRS.mat file, I'm receiving this error:

Arrays have incompatible sizes for this operation.

Error in spm_fnirs_temporalpreproc_ui (line 41)
mask = mask .* P.mask;
Error in spm_fnirs>push_temporal_Callback (line 70)
spm_fnirs_temporalpreproc_ui;
Error in gui_mainfcn (line 95)
feval(varargin{:});
Error in spm_fnirs (line 25)
gui_mainfcn(gui_State, varargin{:});
Error in
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)spm_fnirs('push_temporal_Callback',hObject,eventdata,guidata(hObject))

Do you have any ideas?
Thanks,
