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

AFNI DTIers,
I am finding empty, zero-value voxels in my FA maps that are processed in
AFNI. The input images do not have this problem, so I am wondering if there
is a threshold set within 3dDTeig that would cause this. Is there a no
threshold flag for the command line that could be used to test this?

Thanks,
Brian
