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

We have not processed T2-weighted images much -- the people we work with at the NIH don't use them very often.
How are you evaluating the uniform-ization? By histogram?

One option would be to use 3dUnifize on a T1 volume, and save the scale factor with the '-ssave' option, then apply that scale factor to the T2 volume.
Another option would be to send me a T2 volume, plus a description of how you are judging the quality of the result, and then I can mess with 3dUnifize to see if it can be beaten into doing something more usable.
