dparsf软件提取timecourse的相关问题

Submitted by huyingying on
Forums
各位老师们好:
      我在用dparsf软件提取静息态特定脑区的timecourse时,得出的值基本处于-5~5之间,我想问一下这些值代表了什么含义,是怎么计算出的呢?另外,我想用dparsf软件提取任务态的timecourse,我的做法是把任务态预处理的数据放在FunImgNormalizedSmoothedDetrendedFilteredCovremoved文件夹下,但是不再对这些数据进行Detrend、Filter以及去除协变量处理直接提取特定脑区的timecourse值,不知道这种做法可不可行,如果可行的话我得出的值大概都是800或900,那么这个值又代表了什么含义,应该怎么解释呢。
       谢谢各位老师的解答。
        祝 
      一切顺利

Problem with deleting first images

Dear reader,

I know a similar problem has been reported before, but somehow the solution offered does not work for me.
And parts of the answer was in Chinese so I was not able to follow it completely.

DPARSF nicely starts with processing the DICOM files.
I get a folder called FunImg > Subject > XXX.nii.gz (containing a .nii with 207 images)
But then the following error message appears

超赣,
       您好,我看完你的课程视频,有两个问题想请教
      1. 你在课程中提到多组样本数据比较的时候,要先做ANOVA,然后做Post Hoc分析,但是第一步ANOVA分析以后,这个Post Hoc分析在软件里面又怎么实现呢?
      2.用Rest来做统计分析,如果是同一组人的前后三次以上的测量,数据样本不独立,要做ANCOVA,在软件里又怎么实现呢?

bug report: "DICOM to Nii" when dealing dicom files from GE under linux AMD64

 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.

imput image format for REST v1.4 and DPARSF

Submitted by mcl45 on

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

    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.
