MNELIB::MNEVolGeom records the original volume's dimensions, voxel size, direction cosines and centre RAS - the information needed to convert a surface saved in surf/lh.white back into the RAS coordinates of the originating mri/orig.mgz. Embedded in MGH tag streams and in the headers of FreeSurfer surface files.
