Hi Annie
getting to 0.6mm over the whole brain will be hard and probably not worth it IMO. You could copy either the HCP (0.7mm) or ABCD (0.8mm I think). If you are interested in subfields specifically people typically do somewhat anisotropic 2D scans (e.g. 1mm slices, 0.4mm in-plane) perpindicular to the long axis of the hippocampus. There is some debate over what kind of scans, but I think more people like T2 than T1.

Dear experts, We are currently developing a MRI protocol for a longitudinal study that will take over in the next 3 years using a Siemens Prisma 3T.
We are interested in structural changes within cortical and sub cortical regions, we will also be acquiring DTI and a FLAIR scans. I have seen that for HC subfields .6 mm iso T1 seems to be the gold standard.
Being a new user of freesurfer and trying to make an educated decision regarding our scanning parameters, I was wondering if you have any recommendations regarding the T1 parameters.
Thank you very much,
Annie
