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

The case where applying -weight might be
useful is if there is a high intensity difference
between the base and input volumes. For
example, when running 3dvolreg on Monkey
data, the high intensity muscles around the
jaw have a big effect on registration. Using
-weight with a brain masked volume (not
binary necessarily) can restrict the result
to the actual brain region, giving much better
results (based on the brain, rather than the
jaw muscles).
