What kind of data is this (e.g. acquisition parameters like resolution, TR, and total amount)?

Dear FSL experts,
I'm currently working on resting state fMRI data, and have a short question regarding denoising steps for removing potential noise artifacts due to movement.
So far, after preprocessing I have used ICA-AROMA to remove ICA components identified as motion. Afterwards I regressed out average white-matter and cerebrospinal fluid signals.
Now I want to use movement parameters as nuisance regressors as well and remove them from my data by regressing them out as well.
When regressing out movement artefacts, do I still have to apply ICA-AROMA afterwards?
From my understanding, that would no longer be necessary after all, or does both methods complement each other and make the data even "cleaner"?
Many thanks in advance
Christine
