Dear Yan,

Dear Experts

I would like to genearate a group GM mask by using DPABI's quality control module.

In my understandings, I could generate a GroupMask90Percent.nii based on wAutomask, and then thresholding the mask.

1. How to create a group specific GM mask by using QC module?

In addition, all images must have the same dimension for statstiscal analysis.

If a group GM mask was generated using SPM Masking toolbox, and then reslicing the mask.

      2. The resliced mask looks a little bit different, how to solve this issue?

严老师，您好！

   我在用DPASFA做功能连接时对输出结果有一些疑惑，想跟您询问一下。

   我选取了14个AAL脑区做成一个MultipleLabel的模板，勾选了Functional Connectivity和Extract ROI time course。

   在输出的结果中，FC_FunImgARCWSF文件夹中的SeedSeries和ROISignals_FunImgARCWSF的值不一样。我的理解是SeedSeries和ROISignals应该都是某个脑区信号的时间序列的平均值，请问我的理解对吗，如果不对，那这两个文件实际上对应的是什么值？另外，FC_FunImgARCWSF文件夹中的ROI1FCMap_sub1.nii文件是某个脑区所有体素的信号均值与全脑的连接强度，还是某个脑区的中心坐标的信号与全脑的连接强度？

   期待您的答疑，十分感谢！

Dear Experts

For PT with TFCE, both FDR & Two-tailed were set.

In my understandings, PT were tested at two-tailed P<0.05 with number of permutations being carried out in the analyses. In addition, FDR & FWE were also examined.

Dear Chao-Gan,

in SPM, when a correlation analysis in performed, it is necessary to specify the study design (eg. multiple regression).

I am wondering what is the model used in DPABI->Statistical Analysis->Correlation Analysis.

Thank you,

P.

当运行到将结构像和功能像都转格式成功后，出现如下错误：

Hi

I tried  via define ROI > others ROI> MASK   added  BrainnetomeAtlas_BNA_MPM_thr25_1.25mm.nii   but FC folder in result folder are mistak result  for exampel ROIcorrelation sholde 246*246 Matrix but result me 255*1   and  not exsist  FC regions .

Thank you for helping me where is the problem
