RE: error during temporal analysis
Dear Victor,
Could you inform us of stopband frequencies that you have applied to your data?
Could you also upload the data to this post or send me the data by email?
Thank you for using the SPM-fNIRS toolbox.
Best wishes,
Sungho

Hi Experts:
I analyzed the data collected in my lab following the tutorial of SPM for fNIRS toolbox. I encountered a problem when I perform the temporal analysis.
My data is large (~100,000 time points in raw data). I followed exactly the same parameter settings as the tutorial, especially I intended to downsample it to 1 Hz. However, during the execution of temporal analysis, an error was printed on the screen:
---------------------------------------------------------
Apply temporal filters to fNIRS data...
---------------------------------------------------------
Read and display time series of fNIRS data...
Specify parameters for temporal preprocessing...
Completed.
Apply a temporal filter to hemoglobin changes...
Error using filter_with_correction (line 51)
Calculated filter coefficients have poles on or outside the unit circle and will not be stable. Try a higher
cutoff frequency or a different type/order of filter.
Error in filter_with_correction (line 51)
error('Calculated filter coefficients have poles on or outside the unit circle and will not be stable. Try a
higher cutoff frequency or a different type/order of filter.');
Error in ft_preproc_bandstopfilter (line 283)
filt = filter_with_correction(B,A,dat,dir,usefftfilt);
Error in spm_fnirs_preproc (line 113)
for j = 1:nf, Y = ft_preproc_bandstopfilter(Y', P.fs, P.K.C.cutoff(j,:), forder, ftype, fdir)'; end
Error in spm_fnirs_temporalpreproc_ui (line 155)
[fy, P] = spm_fnirs_preproc(y, P);
Error in spm_fnirs>push_temporal_Callback (line 69)
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 @(hObject,eventdata)spm_fnirs('push_temporal_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating UIControl Callback
==========================
This error was reported after when I observed the motion artifacts correction progress bar disappear. This error could get around by deselecting the cut-off filtering.
Thank you very much!
