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

Note that if t < T0 (or T1), the curve is considered 0.

But what is probably throwing you off is the default
scaling of the curves. Unless AFNI_CONVDIFFGAM_DO_SCALE
is set to 'NO', the base curves are scaled to be unit
height (so if A0=1.0, then the peak is 1.0). If you turn
off that scaling and re-compute and re-plot the results,
they should match.

The peak of the curve happens at time t-T = D*E.
Each curve is rescaled by the magnitude of the curve
at that time.
