 +  <a href=/​reference/​ft_determine_units><​font color=green>​FT_DETERMINE_UNITS</​font></​a>​ tries to determine the units of a geometrical object by
 +  looking at its size and by relating this to the approximate size of the
 +  human head according to the following table:
 +    from  0.050 to   0.500 -&gt; meter
 +    from  0.500 to   5.000 -&gt; decimeter
 +    from  5.000 to  50.000 -&gt; centimeter
 +    from 50.000 to 500.000 -&gt; millimeter
 + 
 +  Use as
 +    dataout = ft_determine_units(datain)
 +  where the input obj 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.
