如何查看xjview的结果？

Submitted by aileenwh on Fri, 02/03/2012 - 23:40

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
149 --TOTAL # VOXELS--
149 Right Cerebellum
149 Cerebellum Posterior Lobe

关于回归协变量

Submitted by xjtu2011 on Sat, 02/04/2012 - 12:25

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！

严老师：
你好！
我在用dparsf成批处理数据时，报了这样的错误：

Error with Detected Time points

Submitted by ahezghia on Fri, 02/10/2012 - 04:56

Hello everyone,

I am just beginning my resting state fMRI analysis, and I have been running into an error. I have created a folder in the working directory called FunImg, where I have added folders for each subject. In that folder, I added the .img file for the resting state scan. Therefore, the file path is created as follows:
Working Directory\FunImg\Subject#\rest#.img
