Dear Dr. Yan and predecessors,
Dear Dr. Yan and predecessors,
实验中我对同一被试进行了两次重复扫描,并用DPABI对这两组数据分别进行了计算,得到了RESULT和S2_RESULT。请问我在统计时应该如何处理这两组数据呢?请问下述的方案可行吗?或者有其他的办法。
1. 把重复扫描的结果当成独立的样本进行统计
2. 取同一被试计算结果的均值进行统计
3. 分别统计看哪个结果更好
老师:
您好!
我是DPABI的初学者,我用的是DPABI3.1,matlab2014b,spm12.
想请教几个问题:
1、在设置time points和TR为0后得到的TRInfo.tsv文件打开得到的time points 是1,但实际time points是150,请问为什么会出现这种情况?
2、在转dicom文件为nifti之后进行其他处理时,无论设置time points为1还是150,都会出现如下错误
请问该如何解决?
3、multiband数据如何设置slice number和slice order以及reference slice?
Good morning,
I am an intern at Ghent University and I am trying to use DPARSF to preprocess my data. Actually, they have already been preprocessed by my colleague, but they still need to undergo some further steps (detrending, filtering, ...). I downloaded DPABI and DPARSF on my computer, I set the paths (I added DPABI and DPARSF with subfolders on Matlab), I loaded my participants and I set all the parameters on DPARSF, but when I tried to run it, it was giving me this error:
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".
请教一下,如果静息态和T1原始数据是hdr+img格式的那怎么进行预处理呢?
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!!
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!
