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,

Thank you for your reply. I followed your steps along with the information here: [afni.nimh.nih.gov] . However, I had massive spikes in my "cleaned" dataset. Another user had the same problem (https://afni.nimh.nih.gov/afni/community/board/read.php?1,148918,148923#msg-148923) in which Gang suggested that this might be due to censoring out time points and thus, 3dSynethesize would not be a good option. He suggested PPI analysis.

Is there any other AFNI tool available to account for scanner drift etc., while also dealing with censored data? I am working with a software that assess whole brain task-based functional connectivity. This software needs one continuous timeseries file. I have four runs of my task-data (censored for motion).
