报错

严老师:
     您好。我在运行DPARSFA时,出现以下错误。请问这是哪出问题了?
Running 'Run DARTEL (create Templates)'
Failed  'Run DARTEL (create Templates)'
Undefined function 'file2mat' for input arguments of type 'struct'.

reho机制

各位老师你好!
    请教一下我们做reho时,在文章中怎么解释其含义,像激活那样解释吗?我看很多文章都说reho的机制还不是很清楚,但最近听左西年老师说他们最近做了个关于其机制的东西,请各位老师赐教。

Structural / Functional Connectivity - Literature Review

Hello,

I am searching for papers discussing the issue on structural connectivity might reflecting functional connectivity (e.g. Greicius, Supekar, & Dougherty, 2009; but not necessarily vice versa; Deco, Jirsa, & McIntosh, 2011).

If somebody made a similar search in the past, I am thankful for any reading suggestions. 

比较初级的问题

 我想问一下,用dparsf做出的reho数据有reho开头的,有mreho开头的,有在reho开头的,具体分析时要用哪一个啊?

大脑和行为之间的关系

各位老师好!
 
我想请教一下各位老师,在fMRI研究中,应该如何来做大脑和行为之间的关系。
 
1, 在一般的高分和低分极端组设计中,似乎通常的做法是这样的:对两个组进行独立样本t检验,对有差异的脑区即ROI提取平均值,比如ReHo的平均值,然后分别在高分组和低分组内做ROI提取的平均值与某个量表的Pearson相关。但是这样做的效果我得到的不是很理想。有时候得不到显著的结果。有时候得到的结果甚至和独立样本t检验的结果互相矛盾。比如,在高分组中发现某个脑区的ReHo值高于低分组,然后组内的Pearson分析竟然发现它的ReHo值与量表得分呈负相关。我觉得可能的原因在于由于在一个组内做分析,样本量太少导致的。
 

Please, helping with a problem calling the datasets from rest toolkit

Dear Resting experrts,

I am getting an error message with Matlab. I think that the problem is that I did not set the path correctly to the folder where I want the results.

First of all, I have downloaded and installed the toolkit in MATLAB in a Ubuntu (Neurodebian) environment.

DPARSFA报错。

老师您好:
      我用DPARSFA caculate in MNI space (warp by DARTEL);准备好相应的T1RAW和FunRaw; 包如下错误:

Index exceeds matrix dimensions.

Error in DPARSFA_run>(parfor body) (line 223)
        if strcmpi(DirDCM(3).name,'.DS_Store')  %110908 YAN Chao-Gan,

Wrong ROI definition when extracting CSF/WM signal etc

Hello, I am receiving a bug when extracting the ROI signals (i.e white matter, CSF) for the nuisance covariates regression. The error appears after slice timing, realignment have been done. The error I received is below, I believe it is due to DPARSFA not being able to find the masks in the working directory. The error only appears with DPARSFA.

mixed effects analysis

 Hello!

I was wondering if there is a tool in REST we could use to carry out mixed effects analyses? 

Thank you
Helen
