| The R-fMRI Network

I just started to do my first resting-state analysis using the REST/DPARSF toolbox. I want to do a seed based functional connectivity analysis. But unfortunatley the an error occurs after I've extracted the ROI time course (for details see below). I am using a Mac OS X (Version 10.8.2), Matlab 2012b, SPM8, REST (Version 1.8), DPARSF 2.1.  Any suggestions?

Extracting ROI time courses over, elapsed time: 10.01 seconds.

Dear all,

I am looking for the papers which used rest fMRI in a block design, like 20 seconds rest and 20 seconds some other task. I mean not the PPI or cluster analysis, but rather standard GLM. Any suugestions?

Thanks,
Vadim

严老师：
您好！dparsf2.2功能强大，与时俱进。但由于比较新手，我只能运行dparsf basic version了，比较谨慎严格。
数据的准备：FunRaw（静息功能像），T1Raw（横断面的T1像）；按照以下设置，定了-1 40 20的roi做FC；

Hello, REST-experts!
I come up against a problem.

I don't understand exactly what types of ReHo-files should I download in SPM5 to calculate specify 2d level (one sanple-t-tast)? Should I use ReHo-maps? Or another ones?

I'm forwarding to your reply!
Best regards, Evgenia.

prof. yan,
I have a question when computing connectivity.
I choose Functional Connectivity in the GUI of DPARSF, and click Define ROI, then click Run. but in the Results file, no correlation matrix can be found.

请教臧老师和严老师关于DARTEL方法进行VBM分析以及slice viewer和xjview不一致的问题

臧老师，严老师：
您们好！我想请教您们几个问题：
1、我使用DPARSFA里的new segement and DARTEL的方法做了一下VBM分析，除了性别、年龄，我还想把全脑体积的影响作为协变量去除掉，但是应该使用原始空间的c1还是使用wc1或者mwc1作为协变量呢？
