Dear Victor,
Sorry for the slow response.
1.5 T is not a problem.
Do you have a companion 1mm T1?
If no: then the main problem is the main recon stream.
If yes: what is the in-plane resolution and orientation? If it’s a high-res coronal, it may help with the subfields. For the thalamus, I’d just use the 1 mm T1.
Cheers,
/Eugenio

Subject: [Freesurfer] Subfield parcellation in 1.5 T and 2.6 mm Thickness
Hi FS developers,
We were wondering whether a MRI scan that has 2.6 mm thickness + is 1.5 T would be sufficient for a subfield analysis (amygdala, hippocampus, thalamus).
Thanks,
