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 Andrew,

I believe that is because of the correlation for that pair of
in AM parameters for that regressor. The first AM pattern is
100 60 60 100 60. The third AM pattern is 60 20 20 60 20.

The correlation between these is 1.0 (subtracting 60 from the
first and 20 from the second yeilds the same result), so you
will not be able to disentangle their effects. They create
identical regressors sets.
