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

Carolin,

> what should I focus on when comparing the results from different basis functions?

I assume that you're referring to the individual level analysis. For the result with TENT per condition (or task), in the output from 3dDeconvolve/3dREMLfit you should have a t-stat for each tent and an F-stat for the overall shape of the hemodynamic response. You can compare the two modeling approaches (TENT vs. GAM) by pitting the statistical inference based on the F-stat from TENT against the t-stat from GAM.
