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.

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

Dear all REST experts:

老师们好：

我按照严老师的dparsfa 的V4模板参数跑了rs fMRI, 没有报错。但是跑完后进行QC的时候发现有几个被试的配准特别差，如下图。我查了他们的静息态和T1都没有问题，想请问一下为什么出现这个问题？是否能纠正以及如何纠正？

恳请老师们能予以帮助，谢谢各位老师。

Prof. Yan,

                 Hei, I want to consult that whether the VBM analysis of DPARSF Advanced Edition in DPABI_V4.2_190919 is based on the processing step of CAT12 of SPM12 ?   

跑了一些没有T1的数据，得到了reho，falff。奇怪的是总是皮层大面积“激活”，其余部分都是“负激活”。也看不到默认网络。请问这种情况应该从哪里找原因呢。谢谢

有一些被试voxel size是1.8 1.8 5，这样的被试平滑核设置为多少才合适呢？

Dear All,

I got the error  when I was performing the pre-processing for the resting data in the DPABI.

Here is the error information:

Error using DPARSFA_run (line 1620)

Index exceeds array bounds.

Error in DPARSFA>pushbuttonRun_Callback (line 1795)

    [Error]=DPARSFA_run(handles.Cfg);
