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

Submitted by Rosalia on Sat, 07/20/2013 - 00:47

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.

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)

Wrong ROI definition when extracting CSF/WM signal etc

Submitted by aperry on Fri, 07/19/2013 - 19:17

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. My data was converted from DICOM --> NIFTI outside of DPARSF, then converted into spm format using freesurfers mri_convert to 208 indiviudal img files.

DparsfA Error

Submitted by SheepY on Tue, 07/16/2013 - 15:04

 各位老师们，同学们：
       我是这方面新手，最近在学习中，我在安装DPARSF中，总是报错，工具包无法加入matlab中，已尝试了各个版本的DPARSF，均无效。
       我使用的是rest v1.7和spm5。
       DPARSF尝试打开，报错如下：

??? Attempt to reference field of non-structure array.

Alphasim cluster size & uncorrected in spm

Submitted by Gea on Sat, 07/13/2013 - 17:29

 First thanks you for your great work!! 

I performed a multiple regression analysis in SPM8 with a behavioral score as vector for a resting state task. 
Then I performed the Alphasim test with T treshold at 0.005 rmm at 3 (for 3x3x3) and here is my doubt.
