Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

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,
I would like to follow this up because I am uncertain about some of my findings.
I am using AM2 with 2 conditions, RT as amplitude modulation and a deconvolution model (TENT(0,14,8)). This results in 2x2x8 beta coefs and tstats. Is it true that the beta coefs 0-7 of each condition reflect the HRF scaled by the mean of AM and betas 8-15 reflect the HRF scaled by deviations of the mean of AM?
-thanks ben
