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

There is a very brief description in this document (Section 4) of some of the models that were available several years ago:

[afni.nimh.nih.gov]
[afni.nimh.nih.gov]

The description there is no more though than the one found in 3dNLfim's help, but it does provide a good overview of how 3dNLfim works. Otherwise, the best place that describes the model is in the source code for each of these models. These are distributed with the rest of the source code and are named model_something.c. You can view the various models here.

[afni.nimh.nih.gov]
[afni.nimh.nih.gov]

There is an environment variable, AFNI_MODEL_HELP_ALL, that will make the signal model function show help, but this is available only for the model_demri3 and the model_diff_convexp models.

Mostly these are simple functions. It's relatively easy to create a model function for your purposes too. After looking at a few examples, I think that the process is fairly clear, but you can ask us if you run into any problems..
