[Homer-users] motion correction

[Chen Zhao]

Hey guys,

 

I am trying different motion correction methods with Homer2 on my data
hoping to find the best way to reject noise. The process option was set
firstly identify artefacts with 'motion_artifacts_by_channel', and then
correct it with wavelet/spline. However when I ran the option following
errors occurred, I don't know where I've done wrong, could anyone help me
please?

 

 

The parameters was set as 'p=0.99' for spline motion correction.

Undefined function 'csaps' for input arguments of type 'double'.

 

Error in hmrMotionCorrectSpline (line 89)

            SplInterp = csaps(t(lst)', dod(lst,idx_ch)', p, t(lst)')';

 

Error in EasyNIRS_Process (line 88)

        eval( fcall );

 

Error in EasyNIRS>runNIRSsignalProcess (line 1022)

[procResult procInput err] = EasyNIRS_Process(hmr);

 

Error in EasyNIRS>popupmenuNIRSsignalProcess_Callback (line 1435)

        runNIRSsignalProcess(iGrp,iSubj,iRun,handles);

 

Error in gui_mainfcn (line 95)

        feval(varargin{:});

 

Error in EasyNIRS (line 43)

    gui_mainfcn(gui_State, varargin{:});

 

Error in
@(hObject,eventdata)EasyNIRS('popupmenuNIRSsignalProcess_Callback',hObject,e
ventdata,guidata(hObject))

 

Error while evaluating uicontrol Callback

 

 

Also when I run wavelet_motion_correction:

'iqr=1.5' for wavelet motion correction.
