what do you mean by a voxel shift?

Hi Freesurfer Experts, In testing mris_reverse, there seems to be a voxel shift. In looking up other freesurfer utitlites I came across xhemireg and surfreg.

Does xhemireg or surfreg call out mris_reverse, causing the same pixel shift issue???
Based on what I can find is it best to run the following: surfreg --s sub001 --t fsaverage_sym --lh --xhemi Would this flip my lh.thickness.fwhm10.fsaverage_sym.mgh file to the other hemisphere?
Thanks, Ajay

Hello Freesurfer Experts, I processed all of my brains through freesurfer 6.0 dev for Linux and warped the surfaces to standardized space. For a handful of subjects I want to perform a left right flip of the cortical thickness files (standardized space) for a group analysis. What is the best way to perform this in freesurfer? I have found a previous post referencing mris_reverse but there was a mention of it being off by a voxel when flipped. I wanted to see if this is still a concern with the latest version? Is there a better way to achieve this goal without rerunning all of freesurfer such as a newer took, or is this the preferred method? Thanks, Ajay
