Fmriprep - further preproc options that are recommended? (ica_aroma, etc) (task connectivity)

  1. how long the acquisition has to be to be considered adequate for the 50% aCompCor you mention?

  2. Beginner-level question: is sth wrong by using both ICA_aroma and aCompCor+GS? Is it thought to be either the one or the other? or using both should not be a problem? I found this kind of open from the search I did so far.

In this post, Confounds from fmriprep: which one would you use for GLM?
I see this point: (no mention for ica_aroma here).

Opinions on this topic are divided and this is why FMRIPREP provides those regressors instead of cleaning up the data for you. I personally would include 6 motion parameters, FD, and aCompCor on run level and mean FD on group level (for both task and rest).

Thank you so much again.
