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

Also note that you CANNOT run 3dNLfim without constraints. If you don't give constraints, the program uses the model's built-in constraints, which you can find in the model_gammavar.c source code. Setting reasonable constraints that will match your data is really important. It is crucial that you set the amplitude parameter constraints to match the range of data that occurs, for example.
