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

Thanks! And sorry for the delayed response. The workaround I'm using for now is just to manually remove the -x1D_stop option from the 3dDeconvolve command generated by afni_proc.py before executing the script. I will look into timing_tool.py as well.

Hi, all,
I just wanted to follow up on this question -- I figure it might have gotten buried since I posted it on a Friday afternoon!
Thanks!

Hello, AFNI mindhive --
I'm currently analyzing a set of fMRI data and am running into some trouble implementing a gPPI analysis. My apologies in advance if a similar question has already been posted -- I couldn't find anything when I ran a search.
(Some background if it's useful: We've got a 2x3 design, and we functionally defined seed regions based on sensitivity to th
