Oh, I see. They are fairly different in the way that they try to place cortical surfaces. Recon-all uses T1 intensities directly, and only works with high-resolution near-isotropic T1w scans. Recon-all-clinical uses machine learning and is compatible with scans of any contrast and resolution, BUT is less accurate than recon-all if you actually do have 1mm T1 data. So, I would try recon-all first. Cheers, /Eugenio

I was more wondering if the standard recon-all pipelines (v8.0) are the same for recon-all clinical, since it seems like recon-all in version 8 uses Synthseg by default. My population is children aged 4-6 years old with cerebral palsy. The T1-weighted scans are MPRAGE, 0.8mm isotropic.

What ages? What MRI sequence and resolution?

Thanks, Stefanie
