Hi Santoucha,

- yes, we would still recommend a CSF regressor. Depending on where you set a threshold RSNs may or may not overlap with CSF

- yes, you can use the single subject preprocessed data for a group Melodic. It's not because you've applied ICA to the data once that you can't do that a second (or third, or...) time.

Best of luck,
Maarten

Hi Maarten,

Thank you very much for your response.
I have read the article Pruim et al., there it says that RSNs exhibited very low overlap with CSF, so I wonder if it is necessary to do a nuisance regression as the next step after ICA AROMA.
I would also like to know if it is true that I can use the output of ICA-AROMA (after further pre-processing/high pass filtering etc.) as the MELODIC input to do a group analysis (temp conc).

Thank you!

Kind regards,
Santoucha
