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?
