Dear Dr. Yan,
I encountered a problem while doing Mixed Effect Analysis. I wanted to add covariates (age, gender and handness). But the problem is that the covariates are the same for both condition 1 and condition 2.
I added as
group1_cov.txt
group1_cov.txt
group2_cov.txt
group2_cov.txt
Then Dpabi ran for hours and gave weired results. I also tried to name the covariates differently but it didn't work either. I wonder what is the proper way to add covariates in Mixed Effect Analysis.
Thank you!
Best Regards,
Mengjiao
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.
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.
