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 Georgios,

My suggestion is what afni_proc.py does, of course. It truncates the
minimum EPI dimension to 3 significant bits, and uses isotropic voxels.
In your case, it would use 3 mm voxels, basically matching the original
voxel dimensions. Since rotations can rotate the 3 mm direction into
the 6 mm axis, I like throwing away the big dimension.

See the afni_proc.py help output for option -volreg_warp_dxyz.
