yes, that controls how finely the surface-based segmentations are
resampled into the volume. The surface is semi-continuous so you can
sample them into the volume as finely as you like. 0.5mm seems to work fine.

Hi,
In PETsurfer gtmseg, there is the --usf (upsampling factor) which is by
default 2, corresponding to 0.5 mm voxelsize. I was wondering if the usf is
recommended to be chosen depending on your mri voxelsize (eg, usf 1 for 1mm
voxelsize of the mri),
