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 Kate,

Sorry to jump in a little late and without reading
all of this (maybe I will tonight). But the 3drefit
operation (before 3dTshift) should have no effect on
the result on disk (meaning "diff *.BRIK" would show
nothing) because the timing applies to the order of
slices on disk, regardless of what the HEAD file
claims I and S are.

The only affect of the 3drefit command should be to
flip the image in the afni viewer.

I think "slice 0" in the viewer might always be RAI,
and have nothing to do with the orientation on disk.
But I am not positive.
