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

Is there some sort of group masking that is relevant here? The dark (higher magnitude) area looks a bit like a coverage intersection box. Are various subjects missing from coverage outside of that? Do you have a group mask? Do you have a group 'sum' mask (add up subjects per voxel)?

EDIT: For reference, it is nice to run something like:
3dMean -prefix QC/mask.mean sub*/*.results/mask_epi_anat*.HEAD

Which is part of the group QC we were using (a few years back) in AFNI_demos/AFNI_pamenc/AFNI_02_pamenc/global_process_outline.txt
