Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_convert_units”.
FT_CONVERT_UNITS changes the geometrical dimension to the specified SI unit. The units of the input object is determined from the structure field object.unit, or is estimated based on the spatial extend of the structure, e.g. a volume conduction model of the head should be approximately 20 cm large. Use as [object] = ft_convert_units(object, target) The following geometrical objects are supported as inputs electrode or gradiometer array, see FT_DATATYPE_SENS volume conductor, see FT_DATATYPE_HEADMODEL anatomical mri, see FT_DATATYPE_VOLUME segmented mri, see FT_DATATYPE_SEGMENTATION dipole grid definition, see FT_DATATYPE_SOURCE Possible target units are 'm', 'dm', 'cm ' or 'mm'. If no target units are specified, this function will only determine the native geometrical units of the object. See also FT_ESTIMATE_UNITS, FT_READ_VOL, FT_READ_SENS
