连通分析中,单个被试激活体积怎么看?
在视频中,我们做一个组的以某个脑区为种子点相关脑区激活体积 ,但我们要看单个被试的激活体积,得怎么看呢?
盼复,谢谢。

我的dparsf是这样设置的,但是RUN的时候出现了下面的问题:
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.
Dear REST authors
Is there a way to perform single or group-level independent componet analysis (ICA) of resting-state fMRI data by using REST ??
Thanks.
Kim
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?
Dear DPARSF experts,
whilie running DPARSF I have encontered the following error reported in DPARSF_run.m:
Error using ==> copyfile
No matching files were found.
Error in ==> DPARSF_run at 551
copyfile('*.ps',['..',filesep,'RealignParameter',filesep]);
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!!
