dpabisurf结构相分析标准化的平滑核以及FWM校正的平滑程度估算

Submitted by Lee on

严老师好,各位老师好,我用dpabisurf做结构相分析的时候遇到些问题,希望能得到各位的解答。请问做表面积以及皮层厚度等指标分析的时候,是否应使用results文件夹里未经预处理平滑的数据,然后在做标准化时进行平滑,这里用多少平滑核比较合适,我参照CAT这个软件用了15的平滑核,不知道是否合适。还有就是我将被试者分为3组,在做统计分析的时候使用ANCOVA统计,多重对比使用的是ISD。在Viewer里面查看并做多重对比校正时,F.gii文件使用FWM查看估算平滑程度时显示为17.285,然后进一步查看F_PairwiseDiff_Z_G1vsG2.gii文件时,FWM显示估算平滑程度为0。这里F_PairwiseDiff_Z_G1vsG2.gii文件做FWM多重校正时估算的平滑核我应该这么调整呢?希望能得到你们的指导。

Dear Dr. Yan

I encountered an error when I ran my data (not have DICOM data, start with FunImg and T1Img) by using DpabiSurf. The data have passed the data organization checcking and successfully converted into BIDS. But, the error was reported during the “Preprocessing with fmriprep” stage for every subject. The error log is the following figure. Since this is not DICOM data, I manually entered TR=2 (but I confirm that this is correct). I confirmed that I have correctly installed the DpbaiSurf as I have successfully run the DemoData (start from FunRaw) posted on this website.

ROI definition for measuring functional connectivity

Submitted by tara.fd on

Hi everyone, 

In a hole-brain study, I need to measure the functional connectivity and I need the results based on the Schaefer atlas. There is not any specific region of interest, then what should I choose in the "Define ROI" box?

I try to choose Schaefer from my system but it doesn't show the file in the folder.

I'll appreciate if you could help me,

Tara

错误使用 copyfile
未找到匹配的文件。

出错 DPARSFA_RerunWithGSR (line 89)
copyfile([Cfg.DataProcessDir,filesep,FunSessionPrefixSet{iFunSession},StartingDirName],[Cfg.DataProcessDir,filesep,FunSessionPrefixSet{iFunSession},StartingDirName,'global']);
