Hi Erik

it's all empirical, but I would think much over 1.5mm in and direction would make it of limited value Bruce

Dear Freesurfer experts,

I'm wondering if there is a minimum voxel size for the T2 iamge to be included in the recon_all. My T1 is .9mm isotropic but the T2 available is 0.5mmx0.5mmx3mm. Would this voxel size offer any benefit or would it be best just to run the recon_all with only the T1 image.

Thanks in advance and apologies for this basic question.

Kind regards

Erik
