Different functional connectivity results

Dear all

 

Hi, 

I'm using DPARSF for 12 subjects. 

Today I found that in one subject, functional connectivity images from all 4 sessions of BOLD resting state fMRI have different image from others. 

Here I attached a screenshot, left one is different from right normal image. 

I did every analysis in same procedure and checked several times. 

It seems like participants moved during measurement, but when I checked a realignment parameter, movement is less than 0.5mm. 

DPARSF error during S2_FunImgARWSFCB

Dear all 
 
Hi, 
I'm using DPARSF for analyze resting state fMRI data from 12 subjects. 
I have an error message after smoothing, from only 1 subject. 
 
Error message :

DPARSF ROI definition

Hi
I m quite new for this field.
I m trying to choose simultaneously AAL and CC200 roi for ROI correlation
FisherZ matrix.
Finally I have 316x316 Matrix (AAL 116 and CC200).
For the next step I hope divide this for 2 matrices.
Which can I divide first 116 or 200 from 316 for each row and column ?

I appreciate any advice

Thank you

Question roi-aise connectivity analysis

Dear all,

I have a question. After making ROI-wise connectivity analysis, we get
three different txt files.

Could you please tell me what do they correspond to?

Kind regards,
Constantin

严老师:
您好!

学生有一个问题请教一下老师,我目前想使用REST计算偏相关分析,但是我在rest界面上没有找到相应的功能按键。例如,假设我目前有ROI1,ROI2,ROI3,我想看一下基于voxel水平的whole-brain的FC,但是会把ROI3的影响去掉。所以我的作法是提取ROI3的时间序列,然后使用REST,进行FC计算,但是把ROI3的时间序列放在txt文档中,作为
covariable,不知道我的作法是否合适,还请老师帮忙解答一下。
谢谢!
