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

Why does normalization amplify this problem? We noticed strange "wedges" of activation in our group maps and in troubleshooting discovered that this was happening in some subjects after normalization with EPIs that looked fine prior to normalization. We're not interested in this slice, so I think we can just delete it prior to the group analyses. Is there any reason not to do this?
