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

Hi Chuck,

In general, it seems fine if you are happy with the results. However if you feel the correction is too severe, there are a couple of ways to get some relief:

(1) A mask will definitely help;

(2) A shorter connectivity radius will also penalize less. In your case of 3.125X3.125X6 mm^3, you can also use 7.5 mm (diagonal of the voxel), 6.1 mm (longest dimension among the 3), or even 4.5 mm (in-plane diagonal), which might be more lenient.
