老师您好,请问审查是怎么进行,我是用的最后一个预处理出来,去掉脑脊液信号的协变量进行,请问是否是这样进行呢?但是导入数据后没有反应,有无教程可以分享呢,感谢感谢!

严老师及各位老师好,我有一些关于dipabi-net的疑问,希望各位老师能指导一下。之前学习做网络属性分析接触的是Gretna,现在在学习dpabi-net,我发现了两个软件有点不一样。在Gretna软件中进行网络分析,Sign of Matrix中sign可以选择positive,negative和absolute,但是在dpabi-net的Graph Theoretical Analysis模块中并没有类似的设置,所以我想请各位老师指导一下,在dpabi-net的Graph Theoretical Analysis模块中分析矩阵时,对于Sign of Matrix的正负值是如何处理的?是将负值设置为零,只计算取值为正的值?还是计算了绝对值?或者是保留了负值代入公式进行计算?希望各位老师能抽空给我指导指导,非常感谢~~~
I am using DPABI to extract the ReHo values of spherical ROIs, with the following settings for MNI and radius: 46 -52 48 5
When you are using DPABISurf, you may encounter:
Error using gifti/save
Too many input arguments.
Error in y_Write (line 73)
save(Header,OutName,'Base64Binary','RowMajorOrder'); %YAN Chao-Gan, 221208. freesurfer needs 'RowMajorOrder' %save(Header,OutName,'Base64Binary');
DPABI Harmonization is an open-source, user-friendly toolkit developed to address the challenge of integrating multi-site neuroimaging data in the pursuit of validity and reproducibility in research.
Hello,
Is it possible to use a custom mask file in DPABI Surf's statistical analysis? When running a two-sample t-test with a mask file I generated, I get the following error:
"As you didn't define SurfFiles, you can only use standard masks such as fsaverage5_lh_white.surf.gii"
This error persists even if I enable PALM with a "Surface File" and "Surface Area File".
Best regards

老师,想请问一下,我在利用dpabi进行MixedEffectAnalysis分析时发现,当我对每一组fMRI数据添加对应协变量(年龄、性别、教育年限)时,跑出来的*_Interaction_F.nii为空白;添加对应协变量(性别、教育年限)不包括年龄时,跑出来的*_Interaction_F.nii图像文件值特别大,达到*10以上,全脑显著;不添加协变量时跑出来的*_Interaction_F.nii就是正常图像,想请问一下为什么,可以解决吗。以下是输入文件情况( ),以及3种情况结果图
