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 Aaron,

There are certainly instances where that would seem reasonable. It would be strange to include 3 or 4 time points early in a run when the next 25 are censored, for example. But coming up with a concrete and reasonable method for exactly when to do such a thing might be difficult, especially since it would depend so heavily on the experiment design. Still, doing such a thing seems justifiable.

We suggest performing the entire linear regression (including just projection) in a single model, which includes band passing and censoring, as well as any other desirable or undesirable components in the model. That is how afni_proc.py does it, so you can use that to see an example if you have not already done so.

Right, it would not be reasonable to band pass kill-mode censored data (unless the band pass terms were similarly truncated - again that is most straightforward to do in one model).
