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

Hi, Russell-

I actually just replied to your NeuroStars question about this earlier today (sorry for the delay); I am posting the content here, as well.

----------------------------------------------

You can use afni_proc.py to include projection onto your FreeSurfer-generated surface as part of your EPI+anatomical processing. This is done by including the “surf” block in afni_proc.py. Your final output stats from your GLM model are then surface dsets; these would give you your “2D+t” maps of EPIs on the surface (fitts* and errts* files), as well as your stats dset output on the surface.

Examples of this are included in the AFNI Bootcamp demos and lectures; you can see AFNI_data6/FT_analysis/s03.ap.surface, which is also Example 8 in the afni_proc.py help:
[afni.nimh.nih.gov]

There is also a video lecture of teaching this in a Bootcamp here:
[cbmm.mit.edu]
… with lectures 24-28 talking about SUMA usage in general, and lectures 26 (starting at about 29:00) through 28 talking about doing the surface projection with afni_proc.py explicitly.

In the AFNI Academy YouTube channel:
[www.youtube.com]
… a set of SUMA-related lectures will also be up soon.
