The R-fMRI Network

Whether multiple comparison correction is required after Correlation Analysis in DPABI?

据说所知，在DPABI里面应用ROI  signal extractor 对mwrp文件进行提取提取的是平均灰质体积，请问如何才能实现计算一个脑区（如海马）的绝对体积或相对体积呢？课题组有师兄是基于AFNI软件用代码实现了脑区内的逐体素相加，DPABI里是否能实现这样的功能呢？

Dear Dr. Yan,

I have a question about changing voxel size.

I want to get ROI signal by applying Yeo atlas.

I have fMRI data with 3mm voxel size but there are only 1mm and 2mm voxel size Yeo atlas.

So I want to change 3mm voxel size to 2mm in the preprocessing process using DPABI.

Could I simply change voxel size on the DPABI like the image I uploaded?

Could you give me some advice on this problem?

Thank you.

I've been doing research on Reho reliability recently.In the meantime, I use DPARSFA for data preprocessing,Then I had some problems.first,Should I choose smooth derivatives?second,if I choose smooth derivatives,I'll get two folders :Results and ResultsS. I will get the mReho,Reho,zReho and smReho ,sReho ,szReho,Which file is generally used to analyze the reliability of Reho?
