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 Irene,

Had there been no jitter in 'c' duration, this would lead to
multi-collinearity problems with many sets of regressors.
While having the jitter may make this mathematically solvable,
the results should not be very robust. What were the matrix
warnings output from afni_proc.py? There were probably many
high correlations.

Basically, in order to use TENT effectively, the conditions
should not follow each other so consistently.
