DPABI/DPABISurf/DPARSF

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 

各位好：

      运用DPABI 处理静息态fMRI 数据，得到了ReHo 图，双样本t检验得出两组差异脑区（岛叶），按照文献的做法，以差异脑区（岛叶）为种子点，做seed-based Functional Connectivity (FC),

DPABI一直报错

    我自己的做法如下；

     1.将差异脑区（岛叶）在DPABI VIEW 界面存为MASK

    2 进入DPARSFA界面 ，选择"Functional connectivity" 和“extract ROI time course”   弹出ROI tempalte 对话框，选择 Define other ROI, 弹出ROI list 对话框， 选择+Mask 选择  岛叶 mask.nii 文件

   但一直报错。

One more thing for protecting The R-fMRI Network (RFMRI.ORG): for users who registered in the last 5 months (if you found you can not log in), must re-register at rfmri.org.

I tried to add the BrainnetomeAtlas_BNA_MPM_thr25_1.25mm.nii atlas to DPABI but structures are not visible in DPABI_VIEW  and below error
