Hi Jidan, I saw your other post, too, but it's not as easy to answer, and I think I've already told you what I know in previous posts about that. Still, I'll take another shot at it later.
This question is easy: You can use the Freesurfer sphere, but the existing parameters in the TEMPLATE_REG-with-POP-AVG_4K_NoFid.deform_map will not work the same as they would with a downsampled mesh. I typically don't get as far as this, because to draw the landmarks needed for registration, you need an inflated surface, and without downsampling, the reference distances used in the Core 6 landmark guidelines don't have the same meaning, because the surface is not as unfolded/inflated as it would be with a downsampled mesh. So you can do it, but the whole core 6 landmarks framework that allows you to compare across studies using the PALS-B12 atlas is in jeopardy. You may not care about this, though.
