Questions about correlation analysis(statistical analysis) in DPABINET

Submitted by DHLee on

Hello, Prof. Yan~!

Previously, I performed correalation analysis using 'statistical analysis menu' in 'DPABI' to calculated R maps(in this case, I calculated voxelwise R maps between fALFF maps and clinical measures). 

Now I am trying to perform correlation analysis using 'statistical analysis menu' in 'DPABINet' to calculate R matrix(containing r-value matrix with clinical measures, ex. 160x160 matrix) associated with clinical measures. 

Therefore, this time, I try to do correlation analysis in edge level, not voxel-level(I try to perform NBS later). 

关于DPARSF/DPABISurf 中“nuisance covariate regression”模块的“other covariates”功能

Submitted by GuoBW on

各位老师好:

          我在使用DPARSF/DPABISurf的过程中,在回归协变量中勾选了other covariate,弹出一个ROI list对话框,添加了一个ROI(mask),但是在运行过程中会出现报错,请问是什么原因呢?(我的目的是探究下丘脑的前部和后部与全脑的功能连接,把整个下丘脑的信号作为一个协变量,即ROI)。

          另外,我发现,在回归协变量中,勾选了global signal(即只做GSR)之后,生成的文件名中是没有global的。我通过处理后的数据看了一下,发现是回归了global signal,只不过是文件名没有带global ,这方面能否进行优化呢?我感觉这个容易造成混淆。

 

            谢谢老师。

            祝好!

皮层模板的信息

严老师好,各位老师好,我想要做surf的脑网络分析,不过surf工具包里给的模板并没有像Dosenbach模板那样提供模板信息,在这里想向老师们求教一下,我去哪里可以获取surf工具包里面HCP-MMP1.labe,Yeo2011_7Networks_N1000.label和Yeo2011_17Networks_N1000.label的模板信息呢?希望能得到你们的指导。

Questions about effice size cohen's f2

Submitted by jujube on

Dear Dpabi experts
 I conducted a paried t-test on RS-fMRI metrics, I got TP.nii and TP_cohen's f2.nii. I am confused about why the effect size map for paired t-test was calculated in the form of cohen‘s f 2 instead of cohen‘s d.
I appreciate your clarification, thanks in advance for your time and reply.

FC_FunImgARglobalCWF and FC_FunImgARCWF folders

Submitted by CHL on
Dear all,
 
I have a simple quedtion about the difference between FC_FunImgARglobalCWF and FC_FunImgARCWF folders.
 
If I'm correct, the former one, FC_FunImgARglobalCWF, is the result without regressing out GSR, and the latter one, FC_FunImgARCWF, is the result after regressing out GSR. 
 
Do I understand the contents of the folders correctly?
 
 
 
Thanks.
 
Best regards,
