FieldTrip

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

  FT_FETCH_SENS mimics the behaviour of FT_READ_SENS, but for a FieldTrip
  data structure or a FieldTrip configuration instead of a file on disk.
 
  Use as
    [sens] = ft_fetch_sens(cfg, data)
 
  Either of the two input arguments may be empty.
 
  The positions of the sensors are specified in a gradiometer or electrode configuration or
  from a layout. The sensor configuration can be passed into this function in four ways:
   (1) in a file whose name is passed in a configuration field, and that
       can be imported using FT_READ_SENS,
   (2) in a configuration field,
   (3) in a data field, or
   (4) in a layout file, see FT_PREPARE_LAYOUT
 
  Allowed configuration or data fields:
   .gradfile      = sensor definition file to be read for MEG data
   .elecfile      = sensor definition file to be read for EEG data
   .grad          = sensor definition from MEG data
   .elec          = sensor definition from EEG data
  
  Allowed configuration fields:
   .layout        = reference to a layout, see FT_PREPARE_LAYOUT
