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

Your covariate 'Perf' does not vary across voxels, so it's not a voxel-wise covariate. Just use -qVars instead of -vVars in 3dMVM. If you've set the 3dRegAna script properly, I don't see any problem with your 3dRegAna result: you may explore further the stuff outside of the brain, but I would not worry too much about it. Use a mask to hide the stuff outside of the brian if you're concerned about its cosmetic effect.

Alternatively 3dttest++ is a better choice for this scenario because it has the updated approach to handling FWE correction.
