GCOR and average motion

AFNI Message Board

Hi AFNI Experts,
I have processed resting state scans using afni (standard pipeline with bandpass filtering) for a group. I was examining the ss_review outputs and noticed a significant positive relationship between GCOR (average pairwise correlation in errts) and average motion. In my sample, gcor and average motion (after censoring) had 0.4 correlation.

In group analysis, would the inclusion of both gcor and average motion as covariates adjust for baseline differences in connectivity?

Thank you.

It is possible that inclusion of both gcor and average motion as covariates would help adjust for differences in connectivity caused by artifacts. We have seen this work in our trial analyses. Is this method guaranteed to work? Of course not – nothing in FMRI is known for sure. And different people (including paper reviewers) will have different opinions on this subject.
