Resting-state fMRI topics

 Dear RESTers:

Recently I used DPARSF to process some functional images obtained from GE HDx 3.0T system, my environment was Ubuntu 9.10 AMD 64 Version, Matlab 2009b, SPM8 and DPARSF 100510.

During converting Dicom to nii step, the system keeps running but nothing was converted from dicom files. 

Maybe it's a bug of DPARSF with linux, all the images were smoothly process in WinXP.

 Dear Beijing Normal University Team,

Dear Sir,

I would like to start using REST v1.4 and DPARSF. Could you please guide me through these two issues:

1. In MATLAB, if my original path setting is for spm8 instead of spm5, would REST and DPARSF work, or do I need to change the priority to spm5?

2. The input fMRI image files that I have is 4D .nii image.  What is the appropriate input image format for REST and DPARSF, and how should they be organized?

Thank you very much in advance.

kind regards,
Meng-chuan

   我的问题：

1. 我是在两个激活区的T值最高点为圆心画球，绘制ROI，能否讨论一下各种ROI的利弊，请问各位在研究中一般是怎么做ROI的呢？
2. Taxonomy upgrade extras: 
   GCA

   FMRI

Dear Chaogan,

       I want to used the Dparsf to process the domenstration data you released recently, but I come across with the problem blow.
       What is wrong with this? Thank you.

Best,

请问，静息态fMRI可以单独应用于某种疾病的研究吗？
还是最好和组块设计的fMRI相结合进行对照分析呢？
最近在进行实验课题的设计，关于老年人认知障碍的组块试验设计有什么建议吗？

严老师您好，
我们最近开始进行脑静息态研究，经验不足，目前使用软件（DPARSF，SPM5 Updates）在MATLAB 7.30（R2006b vista版本）平台上应用DPARSF对自己采集的患者数据进行预处理，但是在进行到slice timing时出现了错误，下面一张图是我用DPARSF进行数据预处理的设置。我们使用的是西门子3T磁共振，图像间隔采集。

Slice Timing Setup:sub-2 OK
Warning: In the directory "F:\soft ware\spm5 2010\spm5-update", spm_unlink.mexw32 now shadows spm_unlink.dll.
 Please see the MATLAB 7.1 Release Notes.
