particularly with respect to 0-based or 1-based voxel counting

I checked. No big problems encountered here. mri = ft_read_mri(filename); cfg = []; cfg.datatype = 'mgz'; cfg.filename = 'test'; cfg.parameter = 'anatomy'; ft_volumewrite(cfg, mri); mri2 = ft_read_mri('test.mgz'); compare mri.transform with mri2.transform, this shows some numerical inaccuracies, but no clear offset issues
