Error in functional connectivity analysis when using DPARSF or REST

Hello, Dear DPARSF team

I ran into some problems when I try to compute functional connectivity when using DPARSF. It gave me error message as following. I tried REST to do FC analysis and got same error message. And it is apparently not due to different preprocessing because I used DPARSF to do the preprocessing. Would you please help me solve the problem? Thanks a lot for your help in advance.

在学习静息态过程中碰到的几个小问题

老师们好:
  在学习了course之后我有几个小问题想请教一下各位老师
  1.关于单样本T检验:用一组病人的mReHo做单样本T检验结果(下图一)与用smReHo做出的结果(下图二)有不同,这样的话可能会导致两个样本T检验时设置两组病人都有显著变化的的并集mask时出现差异,从而影响最后结果,我想请教一下的是我们做单样本T检验时是用mReHo好呢还是用smReHo好?
                                                     

请教一下单样本T检验的问题


老师,您好:
  
  请教一个问题,我有病人组16个被试,利用DPARSF计算其ALFF值,然后利用单样本T检验得到病人组内ALFF显著高于全脑均值的区域A,B,C
  
  问题:如果我想单独得到被试甲的ALFF显著高于全脑均值的区域在哪里,我需要用什么方法,什么检验?刚才我单独利用被试甲或被试乙的mALFF分别做了一个单样本T检验,之后用REST slice viewer发现什么结果都没有。是否是单样本T检验要求纳入被试人数需要大于3个的原因?

盼回答,谢谢!!
