 +=====  FT_CONVERT_COORDSYS =====
 +Note that this reference documentation is identical to the help that is displayed in MATLAB when you type "help ft_convert_coordsys"​.
 +  <a href=/​reference/​ft_convert_coordsys><​font color=green>​FT_CONVERT_COORDSYS</​font></​a>​ changes the coordinate system of the input object to
 +  the specified coordinate system. The coordinate system of the input
 +  object is determined from the structure field object.coordsys,​ or needs to
 +  be determined and specified interactively by the user.
 +  Use as
 +    [object] = ft_convert_coordsys(object)
 +  to only determine the coordinate system, or
 +    [object] = ft_convert_coordsys(object,​ target)
 +    [object] = ft_convert_coordsys(object,​ target, opt)
 +    [object] = ft_convert_coordsys(object,​ target, opt, template)
 +  to determine and convert the coordinate system.
 +  The optional input argument opt determines the behavior when converting
 +  to the spm coordinate system, and pertains to the functional behaviour of
 +  the private functions: align_ctf2acpc and align_neuromag2acpc.
 +  The following input objects are supported
 +    anatomical mri, see <a href=/​reference/​ft_read_mri><​font color=green>​FT_READ_MRI</​font></​a>​
 +    anatomical or functional atlas, see <a href=/​reference/​ft_read_atlas><​font color=green>​FT_READ_ATLAS</​font></​a>​
 +    (not yet) electrode definition
 +    (not yet) gradiometer array definition
 +    (not yet) volume conductor definition
 +    (not yet) dipole grid definition
 +  Possible input coordinate systems are '​ctf',​ '​bti',​ '​4d',​ '​neuromag'​ and '​itab'​.
 +  Possible target coordinate systems are '​acpc'​.
 +  Note that the conversion will be an automatic one, which means that it
 +  will be an approximate conversion, not taking into account differences in
 +  individual anatomies/​differences in conventions where to put the
 +  fiducials.
