cannot extract measures from sample matrices

Can anybody answer the query I posted below one week ago? I also neglected to mention that the error messages below are printed to the matlab terminal.




Cell contents reference from a non-cell array object.


Error in GraphVar_getDialogData>check_StructureName (line 339)

Mismatch between coordinates of defined ROI and Matlab output

Hi everyone, I have the following problem: I tried to compute functional connectivity by using the 'Define ROI' button. As ROI I selected one of the Default ROIs (taken from Andrew-Hannas nodes of the DMN). This Region had the following coordinates: -6 52 2 (radius: 5). However, the following output in the Matlab command window does not fit these coordinates. See the following lines ...


Question about Mixed effect analysis


   我想请教下关于mixed effect analysis的问题。我想看下实验组和对照组治疗前后ALFF差异,做了mixed effect analysis, 其中interaction effect做出4个脑区。我又做了下每个组治疗前后各自的差异,实验组发现5个脑区,对照组发现7个脑区,这些脑区与之前的4个脑区不全相同。我的问题是,是否需要再单独做治疗前后配对样本t检验,还是重点放在interaction发现的4个脑区上就可以了?另外,mixe分析做出的group effect和condition effect意义是不是不大,是否还需要单独讨论?







cannot extract measures from sample matrices

I have read the GraphVar manual - it's all very clear. I want to get used to simply calculating and exporting graph measures using the Conn Matrix files in the sample workspace.  I have loaded just two of the files (to make it quicker) and chosen to calculate measures on the weighted matrices. I chose to extract the Weighted: Strength (UND) values. When I try to do this it just locks the screen and doesn't show anything else (i.e. progress bars). I don't receive any error messages. I have tried on other weighted measures and experience the same thing.


The R-fMRI Wiki

The R-fMRI Wiki is designed to create a knowledge base for DPABI and DPARSF, and eventually for all the resting-state fMRI.


DPABI is a GNU/GPL* toolbox for Data Processing & Analysis of Brain Imaging, evolved from DPARSF (Data Processing Assistant for Resting-State fMRI). DPABI is available at

DPARSF Advanced Edition

DPARSF Advanced Edition is the most commonly used version of DPARSF.


Data Processing Assistant for Resting-State fMRI (DPARSF) is a convenient plug-in software within DPABI, which is based on SPM.

Working Directory

Working Directory is a common concept within DPARSF.

In DPARSF, Working Directory means the upper directory of FunRaw/T1Raw/FunImg/T1Img etc. All the results will be generated under the Working Directory.
