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 Rick,

Thanks for your reply. I am working with a sample of healthy older adults, MCI, and AD patients. All participants in my sample have less than 21% of total TRs censored and < 1 mm max censored displacement. However, it seems that about 44% of my sample have average censored motion values greater than 0.1. So it seems like there is consistent movement occurring throughout the scan in 44% of participants.

The results of an ANOVA suggest that my groups do not differ on average motion per TR or average censored motion values. Does this suggest that the influence of motion on functional connectivity parameters is equivalent across groups? Are there any other steps in preprocessing you would suggest to run to clean up some of the motion-related noise in the dataset?

Thanks,
Jenna
