 +  <a href=/​reference/​ft_determine_coordsys><​font color=green>​FT_DETERMINE_COORDSYS</​font></​a>​ plots a geometrical object, allowing you to perform
 +  a visual check on the coordinatesystem,​ the units and on the anatomical
 +  labels for the coordinate system axes.
 + 
 +  Use as
 +    [dataout] = ft_determine_coordsys(datain,​ ...)
 +  where the input data structure can be
 +   - an anatomical MRI
 +   - an electrode or gradiometer definition
 +   - a volume conduction model of the head
 +  or most other FieldTrip structures that represent geometrical information.
 + 
 +  Additional optional input arguments should be specified as key-value pairs
 +  and can include
 +    interactive ​ = string, '​yes'​ or '​no'​ (default = '​yes'​)
 +    axisscale ​   = scaling factor for the reference axes and sphere (default = 1)
 +    clim         = lower and upper anatomical MRI limits (default = [0 1])
 + 
 +  This function wil pop up a figure that allows you to check whether the
 +  alignment of the object relative to the coordinate system axes is correct
 +  and what the anatomical labels of the coordinate system axes are. You
 +  should switch on the 3D rotation option in the figure panel to rotate and
 +  see the figure from all angles. To change the anatomical labels of the
 +  coordinate system, you should press the corresponding keyboard button.
 + 
 +  Recognized and supported coordinate systems include: ctf, 4d, bti, itab,
 +  neuromag, spm, mni, tal, acpc, als, ras, paxinos.
