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

Another tricky way to show edges is to make surfaces of all the regions and then use suma to draw the surface nodes in the afni GUI.

mkdir surfs
cd surfs
IsoSurface -isorois+dsets -input ../myrois.nii -o mysurfs.gii

Then start afni in the volumetric data directory and suma with the surfaces you just created.
afni -niml ../
suma -onestate -i *.gii -sv ../myrois.nii

In AFNI, set the underlay to some desired dataset. In suma, press 't' for suma to talk to afni, and the surface edges will appear in the afni viewer. You can control the thickness of the edge lines with the Control Surfaces menu in afni.
