Permutation test 报错，请教严老师！

严老师您好：

   我按照您的讲课视频做了two sample t-test的permutation test，但出现了如下错误：

Error using palm_takeargs (line 1880)

Modality 1 has no data.

Error in palm_core (line 33)

[opts,plm] = palm_takeargs(varargin{:});

Error in palm (line 81)

palm_core(varargin{:});

Error in y_GroupAnalysis_PermutationTest_Image (line 102)

palm([TempDir,filesep,'PALMConfig.txt']);

Error in y_TTest2_Image (line 81)

    y_GroupAnalysis_PermutationTest_Image(DependentVolume,Regressors,OutputName,MaskFile,CovariateVolume,Contrast,'T',0,Header,PALMSettings);

Error in DPABI_STAT_TOOL>ComputeButton_Callback (line 519)

        y_TTest2_Image(S, OutputName, MaskFile, ImageCell, TextCell, PALMSettings);

Error in gui_mainfcn (line 96)

        feval(varargin{:});

Error in DPABI_STAT_TOOL (line 42)

    gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)DPABI_STAT_TOOL('ComputeButton_Callback',hObject,eventdata,guidata(hObject)

Error while evaluating uicontrol Callback

我的DPABI版本是DPABI_V2.3_170105，matlab2012b，路径应该没有空格。请教严老师应该如何处理？谢谢！
