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

The +/-z there refer to with respect to the direction z is changing, not whether it goes from I to S or S to I. If the first slice acquired was the most superior and the last the most (or second most, depending on the parity) inferior, AND if the orientation shows S to I (e.g. RAS) in 3dinfo, say, then the timing pattern should be alt+z.

Note that this is a relative comparison between the temporal order of slices and the order of slices on disk. If they are the same it will be '+', if not, a '-'.

What does 3dinfo -orient say about this dataset?
