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

Thanks!

Replying years later in case anyone else is interested... I had the same question, wanting to understand precisely how t-statistics are computed when using 3dREMLfit. To manually replicate a t-statistic you'll need to construct or estimate the correlation matrix R as described in the (handwritten...) 3dREMLfit notes. This matrix is neither saved in output nor explicitly stored in memory by t
