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

That sounds right to me.

Assuming you have the OLay set to the covariate
mean and the Thr set to the Tstat, then the max
intensity (i.e. the value that 'Jump' is based on)
will come from the OLay volume.

The magnitude of the numbers should come directly
from your covariate values (or differences, if
this is a 2-sample or paired t-test). Maybe you
are doing a comparison test, and the differences
are very small, though correlated with the subject
data.

Details of your command and covariate magnitudes
would help clarify this.
