[Homer-users] motion correction

[Scholkmann Felix]

The "csaps" error occurs since you don't have the Spline Fitting Toolbox.
"csaps" is the function to calculate the cubic smoothing spline:

Betreff: [Homer-users] motion correction

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,eventdata,guidata(hObject))

Error while evaluating uicontrol Callback


Also when I run wavelet_motion_correction:
‘iqr=1.5’ for wavelet motion correction.
