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

Yes, that is the formula given in the help output, and is what
is applied. But it is difficult to say much without seeing what
you are doing.

How did you generate the fitts? More importantly, what is
your reverence time series? And what values did you test
with in your R function?

The gamma_model() function looks good to me, including
scaling of the peak to A.

However there may be an issue with -POWELL. If that
is causing difficulty, remove that option or try -BOTH.
