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!
老师:
您好,我将手上的一批BOLD数据在进行预处理时,均没有出现任何报错,但是,当我用DPARSF进行ALFF、fALFF、以及功能连接操作时,matlab则出现了以下报错:
Computing ALFF with: "K:\yz10test\FunImgNormalizedSmoothedDetrendedFiltered\003"
Read 3D EPI functional images: "K:\yz10test\FunImgNormalizedSmoothedDetrendedFiltered\003".??? Out of memory. Type HELP MEMORY for your options.
