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 Ajay,

The the 'N' stands for noise, so it seemed appropriate
to compute it from the noise time series, when all
known signals have been regressed out. I believe it
is often computed from non-brain, non-ghost areas for
the same reason, but that is much harder to automate.

In particular, it did not seem reasonable to include the
correctable motion effects, or even BOLD signals of
interest.

There is an -volreg_compute_tsnr option, in case one
wants to compute it from the volreg output, too.
