There is an error when I use dpabi for ANOVA.I use matlab2011a.

Hi Teacher Yan,

My operating environment:win7, spm12, rest1.8, DPABI_v2.1_160415, Matlab2012a

The data I'm using:ADHD_Peking(just functional part)

When i press the button 'RUN',the result(below):

Here is my data and data stored path,as you said, each subject's fMRI NIFTI image in one directory and I put them in 'FunImg' directory under the working directory.

Here is my DPARSF setting:

Normally, the HRF is non-stationay and differs across regions. How to do the GCA using REST-GCA, especially the signed-path coefficients. Do I have to extract the fMRI time-series before spatial smoothingfrom ROIs and remove the global signal for making the BOLD time series more stationary for GCA??

大家好！

 我用DPABI分析一批静息态数据，在“Nuisance Covariates Regression”那一步勾选了“Both with & without ” global covariates，最后只生成一种结果。之前有人提问过这个问题，严老师在回答时列出了一系列应该生成的文件夹，我跟那个提问者的问题一样，缺少其中的几个文件夹，详见图。其中“FunImgARglobalCovs”文件夹是空的。

我想请问的是，出现这种情况的原因是什么呢？我最后是不是只得到without global covariates的结果呢？

另：我使用的电脑是win10系统，SPM8，DPARSF 4.1 Advanced Edition.

谢谢，祝大家工作顺利~

请教各位，做ICA分析，提取了成分，在同一成分的组间找到了差异脑区，用差异脑区做ROI，提取每个个体相应成分的值(connective strongth)的单位是什么，怎样计算得到的，需要做Z转换再进行组间比较吗？多有打扰，麻烦啦
