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

Hello,

TSNR is the temporal signal-to-noise ratio. And as signal
is good and noise is bad, it is desirable for this to be a
higher ratio. If you look closely at the @ss_review_basic
output (in out.ss_review.txt), you will probably an inverse
relationship between TSNR and average censored motion (which
is to say the average subject motion, ignoring any time
points that were censored).

So subject motion, that which is not censored, will bring
the TSNR down.

In any case, yes, having subjects with higher TSNR should
yield better results.
