class_docstr: This program creates a transform in lta format
  
  Examples
  ========
  >>> from nipype.interfaces.freesurfer import EMRegister
  >>> register = EMRegister()
  >>> register.inputs.in_file = 'norm.mgz'
  >>> register.inputs.template = 'aseg.mgz'
  >>> register.inputs.out_file = 'norm_transform.lta'
  >>> register.inputs.skull = True
  >>> register.inputs.nbrspacing = 9
  >>> register.cmdline
  'mri_em_register -uns 9 -skull norm.mgz aseg.mgz norm_transform.lta'
