error message when using statistical analysis module in dpabi

Hi everyone,

I try to use the statistical analysis module in dpabi, but it always reports some error information when it comes to text covariates regression. I have no idea what is the problem and how to solve it. Could you please help me to cheek up the problem? Thanks in advance.

The error information is as following:

Undefined function or variable 'dLH'.

Error in y_Smoothest (line 86)
fprintf('DLH %f voxels^-3 before correcting for temporal DOF\n',dLH);

Error in y_GroupAnalysis_Image (line 126)
[dLh,resels,FWHM, nVoxels] = y_Smoothest(r_OLS_brain, MaskFile, DOF, VoxelSize);

Error in y_TTest1_Image (line 87)
[b_OLS_brain, t_OLS_brain, TTest1_T, r_OLS_brain, Header] =
y_GroupAnalysis_Image(DependentVolume,Regressors,OutputName,MaskFile,CovariateVolume,Contrast,'T',0,Header);

Error in DPABI_STAT_TOOL>ComputeButton_Callback (line 493)
y_TTest1_Image(S, OutputName, MaskFile, ImageCell, TextCell, Base);

Error in gui_mainfcn (line 96)
feval(varargin{:});

Error in DPABI_STAT_TOOL (line 42)
gui_mainfcn(gui_State, varargin{:});
