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

Sure,
for example, I have a human PET image, with its associated SNR and resolution.
I have a PET image in mice but with a lower SNR and higher resolution.

I would like to add "noise" to the human image in order to fit the mouse SNR and maybe signal distribution.

I hope that this is clearer smileys with beer
