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, Melissa-

Are you wanting to take N subject's 3D ALFF volumes, stack them together into a N-by-3D dataset, and then calculate the voxelwise normalized "Z" value of each, based on the voxelwise mean and standard deviation?

There are different ways to slice the data, and that matters for order of operations and program(s) used.
