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

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

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!

slice timing和realign报错,但能生成相应的文件夹结果,这个结果能否用于后面的分析?

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!

Error when using DPABI-standardization function for single image

Dear all,

When I try to use DPABI-standardization function, I put one image for a single subject and then run the function. It appears the following error:

 Attempted to access Prctile_25_75(2,:); index out of bounds because size(Prctile_25_75)=[1,3].

Error in y_Standardization (line 86)
Median_AllSub = Prctile_25_75(2,:)';

1个团块mask为ROI提取vmhc值结果ROISignals.txt文件2列数值?

为什么1个团块mask为ROI提取vmhc值结果ROISignals.txt文件会出现2列数值?附上该mask和结果文件。会不会是因为该团块靠近左右半球的中间?这两列数值我应该选择哪个列作为我的结果?
