Dear Alfonso,

Thank you so much for your response.

These are the steps I used in my pipeline. I don't have a fieldmap, so I used this pipeline:

'functional_label_as_original'    'functional_realign&unwarp'    'functional_label_as_realigned'    'functional_slicetime'    'functional_art'    'functional_coregister_affine_noreslice'    'functional_label_as_subjectspace'    'functional_smooth'    'functional_label_as_smoothed'    'structural_segment'

However, the noise mask and the structural image don't seem to be registered properly.
