Holger, you might also play with the fill threshold (--fillthresh) option. In the end, it can't be any smoother than your voxel size of course. doug

Dear Freesurfers, Having used mri_label2vol I received a suitable volume that was slightly unsmooth unfortunately. I was looking for a proper command to ameliorate the smoothness of my volume but could not find a solution.

Could anyone give me an advice to cope with that problem?

Any help is greatly appreciated,

Thanks in advance,

Holger
