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.
Thank you very much for your help. I checked afni_proc.py, it seems using 2 too.
So you don't think detrending will remove brain low frequency fluctuation, correct? Afni help said it's a high pass filter so I try to avoid signal loss.
