Re: [RFMRI] Error using y_FD_Jenkinson

Submitted by Anonymous (not verified) on
Ah...you raise an interesting issue -- tell me if this is the error: I did run the analysis once before using interactive reorientation. That analysis pipeline stopped due to a different error that I figured out, but then I decided to re-run the analysis without interactive reorientation, but I did it in the same working directory.

Could I ask a simple question on CARET visualization?

Hi there,
 
I am new to CARET. Could I ask a simple question on CARET visualization?
 
I would like to use CARET to present my two-sample t test activation results in 3D form instead of 2D map from REST sliceviewer. I mapped the results using multi-fiducial mapping (MFM), However, I found the t value of color bar in the 3D map produced by CARET is lower than that in my original 2D map. For example, the higher t value in original 2D map is 4.3 ,but the 3D MFM map is 1.6. So why the t value in the CARET is much lower?

关于DPARSF V2.3的degree centrality的统计方法

严老师:

      您好!近日我使用了DPARSF V2.3进行了degree centrality的数据处理,得到了一批结果,但困扰我的是我应该对哪些数据进行统计学分析。

     如果没错的话,按照之前的经验,好像应该是用“z文件名”的数据进行处理。但是另外一个问题出现了,即不知道加权结果是以什么为加权条件进行计算的,肯请您予以说明!

    感谢您的回复!

Challenges of meta-analysis on resting-state fMRI studies

Submitted by ZangYF on

Activation likelihood estimation (ALE) is a very good method for task fMRI meta-analysis studies (including both within-group between-condition activation difference and between-group activation difference). Although the design of task fMRI studies varies a lot from study to study, most task fMRI studies use very similar GLM method and focus on the local activity of, rather than the relationship between, brain regions. There have been many meta-analysis task fMRI studies.

One sample t-test results of ReHo

Submitted by Yangmei Luo on

Hi RESTers,

I have a question on the one-sample t-test results using ReHo method. We obtained the results using DPARSFA and fed those files whose initial name is sm into one-sample t-test in REST. However, I found the whole brain was ‘activated’, although the results have been corrected by FDR. It is still the same even if I employed more rigorous comparison correction method. Is there any problem in the process of the analysis? How could I deal with such a problem?

Thank you in advance for you kind help. Any help is appreciated.
