VBM系统问题

 VBM只能用于Linux系统吗?

Error using save

Hi,
I tried to save the configuration mat file for running DPARSF, but I got the following error. I simply cannot save it. Any idea? (Note: the path, up to /working/ is correct/present). By the way, I am now using V3.1_141101.

Error using save
Unable to write file
/data2/dparsf_run_maki/working/sub55_compcor_config.mat: No such file or
directory.

DPARSFA V3.0 & SPM12 - templates

 Dear all,

How can I recognize templates in the folder when their names don't say anything? does CC stand for Craddock? What is the difference between ch2, ch2bet and ch2better and what atlas is it? Which of them is Dosenbach?

Thank you in advance.

Regards,

Kasia Więciorek

 

 

 

DPARSF预处理

 数据预处理的最后两步是去线性漂移和滤波,为什么去线性漂移后的结果文件格式是*img/*hdr,滤波完之后文件格式是*nii?

请问在利用ICA进行独立成分分析的时候应该用哪种结果文件?

MICA GUI view problem

 利用MICA进行独立成分分析,选择单被试单成分显示,参数设置如下:

ICA做完后提取FC值的意义

请问各位老师,我关注ICA做完后的某一个网络,之后提取一些脑区的FC值的意义是表示这个脑区在这个网络中的活动参与度吗?有相关的文献支持吗?非常感谢!

关于 FC 和 extract ROI time courses 分开选择

 老师,

您(们)好!

我看了之前论坛记录还有课程,我理解是如果想用DPARSFA计算 ROI-wise 的功能矩阵,只选择 Extract ROI time courses(不用一定同时选择 Functional Connectivity)也可以的,请问能这样理解吗?

非常感谢!

spm中contrast设置

三种条件:任务1,任务2,任务1+2,即任务1、2单独执行和同时执行
检测任务1和2中没有激活,但任务1+2激活的激活区,contrast设置成 1 1 -1 还是1 1 -2
