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

> What is the difference between the partial F-stats from the TENTS and the F-stats from this GLT?

By partial F-stat from the TENTs, do you mean the F-stat 3dDeconvolve/3dREMLfit automatically provides? If so, that F-stat tests whether there is statistical evidence for the signal at any of the 5 tents. As for the test for your GLT

-gltsym 'SYM: +Lure_Obj_FA[1..3]' -glt_label 1 'Lure_Obj_FA'

the F-stat tests whether there is statistical evidence for the *summed* effect of those 3 tents. If you want something similar to the partial F-stat, do the following with double square brackets:

-gltsym 'SYM: +Lure_Obj_FA[[1..3]]' -glt_label 1 'Lure_Obj_FA'
