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

Hello,

While I am not familiar with the details of ICA-fix, it is
supposed to remove unwanted signals. And so it would seem a
bit strange to still regress out motion terms and bandpass
afterwards. Using up degrees of freedom should be a big
question here. How many terms were removed via ICA-fix?
And to run 3dTproject properly, those removed terms should
be passed to it as an additional -ort term.

Regardless of using afni_proc.py or 3dTproject, this step
should be verified with with the authors of ICA-fix. Do
they intend or allow for that subsequent cleaning?


Ignoring all of that, I assume that the X.nocensor.xmat.1D
file was created via afni_proc.py with the -regress_bandpass
option. So that part looks reasonable.

But it would be more comforting if you could additionally
pass the terms removed by ICA-fix, and make sure that is an
operation they find reasonable.
