Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_senslabel”.

  FT_SENSLABEL returns a list of predefined sensor labels given the
  EEG or MEG system type which can be used to detect the type of data.
 
  Use as
   label = ft_senslabel(type)
 
  The input sensor array type can be any of the following
   'ant128'
   'biosemi64'
   'biosemi128'
   'biosemi256'
   'bti148'
   'bti148_planar'
   'bti248'
   'bti248_planar'
   'btiref'
   'ctf151'
   'ctf151_planar'
   'ctf275'
   'ctf275_planar'
   'ctfheadloc'
   'ctfref'
   'eeg1005'
   'eeg1010'
   'eeg1020'
   'ext1020'
   'egi32'
   'egi64'
   'egi128'
   'egi256'
   'neuromag122'
   'neuromag122_planar'
   'neuromag306'
   'neuromag306_planar'
   'itab28'
   'itab153'
   'itab153_planar'
   'yokogawa9'
   'yokogawa64'
   'yokogawa64_planar'
   'yokogawa160'
   'yokogawa160_planar'
   'yokogawa440'
   'yokogawa440_planar'
 
  It is also possible to specify
   'eeg'
   'electrode'
  although for these an empty set of labels (i.e. {}) will be returned.
