严老师:
DPARSF里有Extract AAL time courses (90 regions)这个选项,这个该怎么分析呢?是不是小世界分析啊?能不能指教一下怎么分析,谢谢!
Dear Dr. YAN Chao-Gan
I've successfully performed seed-based (hippocampus, PAG, and so on) functional connectivity by using DPARSF with default settings.
Now I'm trying to compare FC differences between patients and control subjects.
I have 2 questions.
各位老师:
新年好!元宵节快乐!
我有一个疑问,在DPARSF做功能连接时,有一步要回归协变量,我在想后面的提取ROI时间序列和功能连接,是不是都在回归了协变量之后做的处理?那在统计分析的时候,双样本t检验还要输这些协变量文件吗?
谢谢老师!
请教一下,做组块时,查看脑区激活,在xjview中如何分析?
例如一下的一个cluster该如何分析?
Cluster 1
Number of voxels: 149
Peak MNI coordinate: 45 -63 -36
Peak MNI coordinate region: // Right Cerebellum // Cerebellum Posterior Lobe // Tuber // undefined // undefined // Cerebelum_Crus1_R (aal)
Peak intensity: 3.7961
# voxels structure
