Dear Experts,

I would like to use dpabi for a functional connectivity analysis using an ROI approach. I have two subject groups and I want to conduct a region to region connectivity analyses based on the ROI_FC maps off line.

 I have done two analyses to check my data : 1) I have run both subject groups separately through the dpabi pipeline and 2) I also ran the data of both groups ( as one single group) through the dpabi pipeline. When I looked at a single subject ROI_FCMap file, the connectivy maps have  different values between these analyses.

Dear DPARSFA team,

first, I would like to thank you for your efforts with DPABI, I enjoy working with the toolbox. I hope I’m not sending questions that were already discussed and solved in the forum that I just hadn’t seen.

I encountered two problems for which I am kindly asking for advices.

严老师您好！我用dpabi分析2组静息态数据，2组被试用的机器不同，一组是在高原采集的，一组在平原采集的，用的permutation test/tfce 发现结果差异很大，且结果出现在脑沟里，我重新检查了分析过程（配准都没有问题）重复了2次都是相同的结果，想请教您我需要怎么调整呢？以下为校正后的结果图，期待您的回复，谢谢您！

1.请问各位老师，任务态fMRI为什么一般是在一阶分析的时候做高频滤波，而静息态fMRI一般是在预处理的时候做低频滤波？

2.为什么任务态fMRI一般是在一阶分析的时候加入头动变量，而静息态fMRI是在预处理的时候去除？

3.为什么任务态fMRI在预处理的时候一般不去除白质、CSF等信号？

Hi, 

I'm a beginner user of Dpabi and DPARSF.

now I'm trying to preprocess fMRI data using DPARSF.

After a few attempts, I finished the process, but I think the results seems little bit strange(preprocessing step-attached photo)

I found that there would be  no error message during the process. 

I am studying brain connectivity of children in age-range 7-18 years, and I want to use children atlas instead of DPARSF default atla.

I'm studying children's brain connectivity between the ages of 7 and 18 and want to use the children's atlas instead of the default DPARSF atlas. How can I import my desired atlas to DPARSF? What files and in what formats (e.g. .img of .nii) do I need to enter in this toolkit (DPARSF) for this purpose?

best regards

how can i import our desirable brain atlas (for example children atlas) into the DPARSF?

which fiels need and should be imported for this purpose?

To whom it may concern, 

Hi. I'm a new user of Dpabi and Dparsf for investigating FC of brain network. 

I have a question about preprocessing steps using DPARSF. 

I want to acquire both GSR(Global signal regression) processed data and no-GSR processed data.

So, in Dparsf, I selected 'Both with & without ~' in Nuisance regressors(WM, CSF,Global) section. (attached photo)

But, the results only shows that the data contain only no-GSR processed data. (attached photo)

My desktop OS is Windows 10. 

Dear all,

If you have earned a PhD degree in China in the last 3 years and would like to do a Postdoc in an interdisciplinary and internationally competitive environment at Karolinska Institute in Sweden, please see the project below:
