AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

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.
