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 all,

I am not quite sure where the problem is but I suspect that John is referring to the potential for aliasing when downsampling the response to a low TR.

If that's the case, then John is correct, the downsampled time-series created by waver will have aliasing. However, you don't want to remove the aliasing because you are using these time series to model a signal that would be aliased too.

I hope that helps.
cheers,
z
