Nilearn: about the preprocessed steps of ward parcellation

1

Hi nilearn experts and users,
I am trying to do the hierarchical parcellation on fmri resting data, and i am not sure if i should do the filter steps and clean the noise from white matter and the cerebrospinal fluid. And can i do these things by nilearn?

if you have extracted noisy signals before. Then you can give them to confounds argument while fit ing the hierarchical parcellation on fmri data. Or You can use clean_img with confounds as noisy signals to clean them before.
