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

-trk_opp_orient :If outputting *.trk files, you can choose to oppositize
                     the voxel_order parameter for the TRK file (only).
                     Thus, when inputting AFNI files with orient RAI, the
                     *.trk file would have voxel_order LPS; this is so that
                     files can be viewed in some other software, such as DTK.
