Re: [Freesurfer] Setting the origin in native space

try using the switch: mri_convert -rt nearest ... to use nearest neighbor interpolation (which is what you need to resample a segmentation volume) cheers Bruce On Sun, 6 Jan 2019, Nillo, Ryan Michael R wrote: External Email - Use Caution Thanks for your help, Bruce. This
