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:

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

Dear,
when I look at 3dinfo's output for a dataset, I just get a little confused by the conflicting orientation, just like this:
Data Axes Orientation:
first (x) = Right-to-Left
second (y) = Posterior-to-Anterior
third (z) = Inferior-to-Superior [-orient RPI]
R-to-L extent: -102.774 [R] -to- 105.914 [L] -step- 3.312 mm [ 64 voxels]
A-to-P extent: -89.485 [A] -to- 119.203 [P] -step- 3.312 mm [ 64 voxels]
I-to-S extent: -44.866 -to- 110.822 [S] -step- 3.312 mm [ 48 voxels]
It's RPI at above, while it's RAI at below, and I also find it's not only for this dataset, but actually a common one, which one should I believe?
Thanks,
Peng Ren
