Error using CompCor

Submitted by Emilia Cheladze on
Hello!
I have ​resting state ​data acquired with ​the ​following scanning parameters: TR 2.3, vox size 3x3x3​,​​ and ​I am doing an analysis using DPRSFA V_2.1 and Matlab 2015b​. ​I am reslicing the voxel size ​to ​4x4x4 ​during ​the ​normaliz​ation step (this is so I can compare this data with another resting state data set at the group level)​.

Activation outside the brain

Submitted by Emilia Cheladze on
Hello!
I am doing an analysis using DPRSFA V_2.1 and Matlab 2015b.​ ​Unfortunately, when I complete the below-described analysis, ​I ​am getting​ ​significant ​activation outside of the brain​ (please see ​the picture in ​the ​attachment​)​. ​Would anyone know what could be the cause of th​is​? 
 
​To describe my analysis, ​I have data from two groups of subjects, acquired with different scanning parameters.

degree centrality

Hi, professor Yan,
 
    I did the degree centrality using your dparsfa , after the pre-process of data, I got a two Z-value in the results(called zDegreeCentrality_PositiveBinarizedSumBrainMap_de01 and zDegreeCentrality_PositiveWeightedSumBrainMap_de01 respectively), so which one should I choose to do the statistics, especially for the correlation analysis parts.

请教关于ANOVA和AlphaSim校正的问题

严老师: 
   您好, 我最近刚开始接触fMRI,听了很多遍您的讲课视频,但还是有几个困惑,还希望严老师能在百忙之中帮忙解答: 
 
    一、用最新版DPABI对三组数据进行ANOVA分析时,同时进行了post-hoc,您在最新的视频教程里说到post-hoc是已经经过校正的,那么在看ANOVA结果时P值如果选择0.05的话,再看post-hoc结果时,P值是用0.05还是0.016 (0.05/3)呢? 
   二、进行Alphasim校正时,您说现在Voxel P value应该是0.001,那么在看Al
