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 all,

We are trying to subtract aligned pre- and post-treatment T1 anatomical scans to look for structural changes, but are encountering large between-session differences in overall voxel values and voxel value variance.

Is there an AFNI tool that will normalize a single volume to a specified mean and SD, preferably using a mask to restrict the analysis to brain?

Thanks for any help.
