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

Hello Gaurav,

You'll have to look into the matter yourself since ringing depends on your data and the method with which you perform the filtering. Our recommendation is in the implementation in afni_proc.py which is based on the algorithms detailed in Jo et al 2013. Ringing should not be a matter of concern since we usually bandpass and censor the data in a linear regression framework.

cheers
