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.
