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 everyone,

Thank you for accepting me into the community. I came across an oddity that I wanted to clear up. By default the tshift option in afni_proc.py will put the reference volume at t=0 while 3dTshift itself has the default reference volume at TR/2. Most commonly and mathematically plausible would be the TR/2 option, so I was wondering what the reasoning is, in putting it to the first volume?

Thanks for the help.
