Functional Connectivity Statistical Analysis

Submitted by schlaugummi on

Hello everyone!

I'm new to this topic and am struggling with the statistical analysis of my resting state data. Right now I'm testing the toolbox with only two of my subjects. When I try to add the FC-results to the Group images for a two-sample-t-test, it says [464] in front of the pathway (2*116 ROIs for the two subjects) instead of just [2] for the two subjects, as it was displayed in the tutorial. Do I need to organize the FC-results in any way, before I can use them?

Also, is it necessary to use covariate images for the analysis?

Statisitcal Analysis Interaction Effect in Mixed-Effects

Submitted by winsonfzyang on

Hello everyone,

I am using DPABI statistical analysis to run Mixed-Effect Linear Model.

These are my groups:

G1C1
G1C2
G2C1
G2C2

I’m not sure how to interpret the interaction effect? What does it represent? Is it the group difference in the change? If so, what is the contrast effects (i.e. change in G1 – change in G2?)

Regards,
Winson

 

Error in Quality Control

Submitted by schlaugummi on

Hello everyone,

I'm relatively new to analyzing resting-state data and have a problem with quality control. When I try to do the QC on Raw T1/Fun I get the Error message "Cannot find D:\ProcessingDemoData\QC\RawT1ImgQC.tsv". Can anyone help me out? I use Matlab R2019b and the Demo Data to learn how to use DPARSF.

 

Thanks in advance,

Julia

calculate in individual space

Submitted by Hui Z on

Hi Prof. Yan,

       I have a mask which created based on a previous task fMRI (in MNI space), now I want to transfer this mask to individual space and extract ROI time series of resting data for each subject, I want to know that can DPABI help me to transfer the mask (in MNI space) to individual space? And how can I do this. Thank you very much!
