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.
What version of AFNI are you using? I just realized that there is a bug in the most recent version of 3dMVM that may impact on the F-stat if all factors are between-subjects. But it should not have any effect on t-stat. The two different results about GLT were run with different versions of 3dMVM?
