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 Yi,

There are two approaches to handling your case:

1) At individual subject level, test the linear and quadratic trends among those four levels:

[afni.nimh.nih.gov]

and then take the effect estimates (beta values) for the trends to group levels using 3dttest++ or 3dMEMA.

2) 3dLME.R can handle this directly at group level, but I'm still working on the interface.
