为什么我的mask图像是方形,完全不是头颅的形状

为什么我的面具图像是方形,完全不是头颅的形状
我检查过,在我进行质量控制模块时,我的T1Img,FunImg,以及标准化后图像都是正常的,但是我的面具文件里的图像都特别奇怪,完全不是形似头颅,而是方块形的的,求老师们给我一些建议,可能是哪里出问题了,还有就是我不知道这个论坛,怎么发图片信息?

How to add covariates in Mixed Effect Analysis?

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,

GraphVar_2.01 GLM panel

Hello!

I read GraphVar_SPSS_GLM_validation and GraphVar_Manual but I don,t know GLM panel.

Could you explain me the difference between them(between covariate,nuisance covariate,within covariate)?

All the best,

Group gray matter density mask

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.

DPASFA做功能连接时的输出文件

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!
