[Homer-users] Error displaying HRF when stimulus 2 (of 5 total) is checked

[Perdue, Katherine]

Hi Austin,

How many channels do you have? Have you tried recalculating the HRF, in case the data got corrupted? Do you get the error if you try to display any HRF that is not 1?

I have five stimuli (none are named – just defaults to 1-5)
Any suggestions on how to figure out the cause of my error below.
When I try to display HRF for a second stimulus I get the following error:

Index exceeds matrix dimensions.
Error in EasyNIRS_DisplayData (line 139)
                d = procResult.dcAvg(:,:,:,iS) * sclConc;
Error in EasyNIRS>popupmenuCondition_Callback (line 541)
EasyNIRS_DisplayData();
Error in gui_mainfcn (line 96)
        feval(varargin{:});
Error in EasyNIRS (line 43)
    gui_mainfcn(gui_State, varargin{:});
Error in
@(hObject,eventdata)EasyNIRS('popupmenuCondition_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating uicontrol Callback


Here is line 135-142 which shows procResult.dcAvg as four dimensions:

   elseif hmr.plotHRF==HRF_RUN_CONST
       procResult = hmr.procResult;
       iS = hmr.stim.CondRunInd(iF,hmr.plotCondition);
       if iS>0
           d = procResult.dcAvg(:,:,:,iS) * sclConc;
           if hmr.plotHRFStdErr==1
               dStd = procResult.dcAvgStd(:,:,:,iS) * sclConc;
           end

When I check procResult I find that procResult.dcAvg is three dimensions:

K>> disp(procResult)
        dcAvg: [221x3x5 double]
