FT_SENSTYPE

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

  FT_SENSTYPE determines the type of acquisition device by looking at the channel
  names and comparing them with predefined lists.
 
  Use as
    [type] = ft_senstype(sens)
  or
    [flag] = ft_senstype(sens, desired)
 
  The output type can be any of the following
    'ctf64'
    'ctf151'
    'ctf151_planar'
    'ctf275'
    'ctf275_planar'
    'bti148'
    'bti148_planar'
    'bti248'
    'bti248_planar'
    'bti248grad'
    'bti248grad_planar'
    'itab28'
    'itab153'
    'itab153_planar'
    'yokogawa9'
    'yokogawa64'
    'yokogawa64_planar'
    'yokogawa160'
    'yokogawa160_planar'
    'yokogawa440'
    'neuromag122'
    'neuromag122_combined'
    'neuromag306'
    'neuromag306_combined'
    'babysquid74'         this is a BabySQUID system from Tristan Technologies
    'artemis123'          this is a BabySQUID system from Tristan Technologies
    'magview'             this is a BabySQUID system from Tristan Technologies
    'egi32'
    'egi64'
    'egi128'
    'egi256'
    'biosemi64'
    'biosemi128'
    'biosemi256'
    'neuralynx'
    'plexon'
    'artinis'
    'ext1020'             this includes eeg1020, eeg1010 and eeg1005
    'eeg'                 this was called 'electrode' in older versions
    'meg'                 this was called 'magnetometer' in older versions
    'nirs'
 
  The optional input argument for the desired type can be any of the above, or any of
  the following generic classes of acquisition systems
    'eeg'
    'ext1020'
    'biosemi'
    'egi'
    'meg'
    'meg_planar'
    'meg_axial'
    'ctf'
    'bti'
    'neuromag'
    'yokogawa'
    'itab'
    'babysquid'
  If you specify the desired type, this function will return a boolean flag
  indicating true/false depending on the input data.
 
  Besides specifiying a sensor definition (i.e. a grad or elec structure, see
  FT_DATATYPE_SENS), it is also possible to give a data structure containing a grad
  or elec field, or giving a list of channel names (as cell-arrray). So assuming that
  you have a FieldTrip data structure, any of the following calls would also be fine.
    ft_senstype(hdr)
    ft_senstype(data)
    ft_senstype(data.label)
    ft_senstype(data.grad)
    ft_senstype(data.grad.label)
