It is also worth mentioning that ITK-Snap mesh generation of sub-domains uses NIFTI world coordinates. When ITK-Snap computes mesh coordinates along the x-axis as it does so as: x_mesh = nifti_sform_matrix*[x_voxel;1]. The variable nifti_sform_matrix is the standard reference transform that contains the volume and alignment coordinates of the dataset. We assume there is isometric conversion from voxel space to tetrahedral space based on the coordinates computed for mesh generation. We always check the axes grid of our meshed output in Paraview. We look for a match between the 'Origin and Orientation data' in ITK-Snap and that of the axes grid in Paraview:
