Difference between Segment and NewSegment+DARTEL

Submitted by guiziwu on Sun, 03/17/2019 - 08:33

Dear DPABI experts,

I am confused when I want to normalize the functional images using T1 images from each subject, whether to select "Segment" or "NewSegment+DARTEL".

老师好，我想问一下有关DPABIsurf的问题

我在matlab上运行出现错误。

错误使用copyfile，未找到匹配的文件。我看了下代码，是未找到fmriprep的文件夹。

我怀疑是不是Docker和fmriprep这两个没弄好。但是我不太会弄了，请老师抽空帮我解答一下，谢谢老师。

Paired-t test 放入的 Text Covariate, 是否可以當成影響Paired-t test結果的變數 ?

Submitted by Tony Xu on Mon, 03/11/2019 - 14:46

老師您好!

想請問一下，

當我在分析介入前後，Functional Connectivity的差別時，對同一組人做介入後與介入前相減的paired-t test時,

分別以對應後測與前測放入生理參數(心率變異度的RMSSD)作為Text Covariates

請問這樣所得到paired-t test結果顯著的Cluster，可以解釋為:

1. 介入後所增加的功能性連結會與RMSSD的變化有相關性嗎 (因為是將RMSSD這個前後變化的因素考慮進去所得到的結果)

2. 介入後所增加的功能性連結是排除了RMSSD的變化，所以paired-t test結果顯著的Cluster是和RMSSD這個前後變化的數值沒有關係的

請問一下我對 paired-t test 結果顯著的Cluster的理解應該1.是對的，還是2.是對的呢 ?

謝謝!!

A question about file names of the result

Submitted by 3MCIpawns on Mon, 03/11/2019 - 13:35

Dear Dr. Yan and DPARSF-users:

After I finished the processing steps in DPARSFA, I found that there are 3 different ROI signal files with ".mat" in the result folder. You can see them in file attachments.

I wonder the difference among them and, if I want to use the time courses of ROIs to make correlation analysis, then which file should I use?

Thank you for considering my request!

Best wishes!

老师，您好！我在用dpabi运行slice timing和realign都报如下错误，这个是什么意思？但即使是报错，照样能生成相应的文件夹结果，这个结果能否用于后面的预处理？十分感谢！
