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

  FT_REALTIME_COILLOCALIZER is a realtime application for online tracking
  of MEG localizer coils.
 
  Use as
    ft_realtime_coillocalizer(cfg)
  with the following configuration options
    cfg.blocksize  = number, size of the blocks/chuncks that are processed (default = 1 second)
    cfg.channel    = cell-array, see FT_CHANNELSELECTION (default = {'MEG', 'MEGREF'})
    cfg.bufferdata = whether to process the 'first or 'last' data that is available (default = 'last')
    cfg.jumptoeof  = whether to skip to the end of the stream/file at startup (default = 'yes')
 
  The settings for extracting the spatial topgraphy of each coil are configured as
    cfg.coilfreq      = single number in Hz or list of numbers
    cfg.refchan       = single string or cell-array with strings
 
  The source of the data is configured as
    cfg.dataset       = string
  or alternatively to obtain more low-level control as
    cfg.datafile      = string
    cfg.headerfile    = string
    cfg.eventfile     = string
    cfg.dataformat    = string, default is determined automatic
    cfg.headerformat  = string, default is determined automatic
    cfg.eventformat   = string, default is determined automatic
 
  Some notes about skipping data and catching up with the data stream:
 
  cfg.jumptoeof='yes' causes the realtime function to jump to the end
  when the function _starts_. It causes all data acquired prior to
  starting the RT function to be skipped.
 
  cfg.bufferdata=last causes the realtime function to jump to the last
  available data while _running_. If the realtime loop is not fast enough,
  it causes some data to be dropped.
 
  If you want to skip all data that was acquired before you start the
  realtime function, but don't want to miss any data that was acquired while
  the realtime function is started, then you should use jumptoeof=yes and
  bufferdata=first. If you want to analyse data from a file, then you
  should use jumptoeof=no and bufferdata=first.
 
  To stop this realtime function, you have to press Ctrl-C
