Hello Johann, 

I've noticed that some graph theory studies use parametric statistics and others non-parametric. I am not sure how they checked for normality of graph metrics. Is there a way in GraphVar to check the distribution of the graph metrics in order to determine whether to run parametric or non-parametric statistics?

Thanks in advance!

Dear DPABI experts, 

尊敬的严教授及团队成员，

你们好，非常感谢你们打造了这款软件！

我在使用它时遇到了一点问题（苹果系统），在使用V4模版处理数据时，程序报告了如下错误。

Hi Prof. Yan,

       I have a mask which created based on a previous task fMRI (in MNI space), now I want to transfer this mask to individual space and extract ROI time series of resting data for each subject, I want to know that can DPABI help me to transfer the mask (in MNI space) to individual space? And how can I do this. Thank you very much!

Dear DPARSFA experts

I am novice to DPARSFA tool and using it for resting state analysis. While trying for trial subject, I got following error. Let me align you with my existing pipeline. I am using Matlab19a, SPM8 and Data Processing Assistant for Resting-State fMRI (DPARSF) Advanced Edition (alias: DPARSFA), Release = V4.5_190725.

Dear Colleagues,

各位老师：

您好！想请教您关于Function Connectivity ROI的问题，我是通过rest来做的，也看了rest的course，但是关于ROI的使用有些问题。

视频中的ROI 制作是通过AAL或Brodmann，但是我现在有2-3个感兴趣的区域，每个区域都是一个半径为6mm的小球且球心对应的MNI坐标都已知。如果我要做这样一个ROI mask（包括2-3个小球）用REST软件可以做吗？具体是在哪里找到定义ROI 的GUI呢？谢谢啦！

希望能收到您的回复，非常感谢您！

Hi ALL,

I am desperately need your  advice and know how here.

I have done ROI extraction for 36 known peak coordinates and I have seen within the results' folders that the ROI correlation matrix is given  as , i.e 36 X 36 , which is okay and good but this matrix was done  by subject basis, i.e. one subject per folder.

My PhD SV wants me to produce OVERALL cross correlation matrix per overall group basis as whole. May I know whether DPABI statistical analysis tool can be used and if YES, HOW?

Dear Experts,

I ran an ALFF and fALFF analysis on a dataset with 3 different groups. Now I noticed that my the ALFF analysis yielded very different results than the fALFF analysis, i.e. fALFF shows a very strong difference between two of the groups, while ALFF shows no difference at all. 

Should I be worried about this difference? 

If this is normal, how can I explain and interpret this difference?

Thank you for your help.

Kind regards,

Theresa

I'm new to dpabi. I find it a very interesting tool.

Is there anywhere a manual for dpabi?

Specifically I need help as to the statistical analysis. 

I saw the course, but there is no details there as to how to insert covariates (format ect), how to correct for MC, what are the implementation of using the different files created (z, m, ect)

Any link to clear descriptions will help

Thanks
