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 Rick,

I am sorry to come back to this post so late. Somehow, I was not notified by any email alert about your reply.
360 TRs are from four separate runs. The stimulus lasted about 60 seconds in each run. In this case, what is polort for 3dDetrend and for 3dDeconvolve? The new script for PPI looked so different from mine which was created by the suggestions in this website (https://afni.nimh.nih.gov/sscc/gangc/PPI.html). If I want to stick to own script, were there any critical steps from the new script should be included in my script? Thank you very much.

Best,
Veda
