DPABI/DPABISurf/DPARSF

Hi, I have a few questions about the general linear modeling (GLM) and statistical analysis by using DPARSF.

1. Which step or button of the GUI with Template Parameters perform the GLM? Do we need to perform GLM in resting state fMRI data?

2. If we do, how can we visualize the results of significant regions?

老師您好

I am a MAC OS user. As you suggested  I'd run MATLAB with terminal and successfully finished bet function.

However there is a warning message that I can't resolve:

Hi 

I just tried running DPABI on RS fMRI data, but after orientation step and running the next steps, I got the error message I copied here. If you can help me how to interpret and fix that I really appreciate that.

严老师您好，

         我想请问一下dpabi能否处理小鼠的数据？我看了您的视频教程，里面简单地介绍了大鼠和猴子的处理，请问dpabi有小鼠大脑的模板吗？如果处理小鼠的数据是否有什么需要注意的地方呢？感谢您的解答！

Dear Prof Yan

I have some questions about statistical analysis.

In our study, all patients were assigned to three groups, with two different medication treatment and one medication-naive control. And all these patients accepted MRI scan at baseline and after 12 weeks. Now, my question is as followings:

1. Can we compare the group × time interaction effects on brain activity indicators by repeated measures ANOVA, such as ALFF,fALFF and ReHo. At first, I try to do this by mixed-effects comparison, but it can only treat two factors.

各位老师好！

          尊敬的专家：

                    您好，我通过dpabi中的Extract ROI courses 对AAL、哈佛牛津地图、CC200等4个地图集进行了ROI区域时间序列提取，我想知道的是dpabi在提取ROI时间序列的时候，是通过什么样的计算方式。是分别对每个ROI区域内进行标准化后输出吗？（减均值/标准差），还是通过其他方式？第二个问题，如图所示，ROI Signals_Sub_XX.mat 是每个ROI区域的时间序列吗？   在视频中我并没有看到这一点的讲解，我对ROI提取十分感兴趣，期待您的答复！

        祝您工作愉快！

Hi,

When running DPARSF with the attached specifications, we are asked to manually reorient the image (see screenshot).

Is this something normal/correct, or can it be avoided?
