Hi Manuel, smoothing is usually only necessary for surface data.
You should have crated the subfields on top of the longitudinal directories, so: > recon-all -long <tpid> <baseid> -hippocampal-subfields-T1 > Else they will only be available in the cross dirs. The longs will have better reliability.
