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

  REALTIME_ASAPROXY reads continuous data from the ASA acquisition system
  and writes it to a FieldTrip buffer. This function uses the
  NeuroSDK software, which can be obtained from ANT.
 
  The FieldTrip buffer is a network transparent server that allows the
  acquisition client to stream data to it. An analysis client can connect
  to read the data upon request. Multiple clients can connect simultaneously,
  each analyzing a specific aspect of the data concurrently.
 
  Use as
    realtime_asaproxy(cfg)
 
  The configuration should contain
    cfg.channel              = cell-array, see CHANNELSELECTION (default = 'all')
 
  The target to write the data to is configured as
    cfg.target.datafile      = string, target destination for the data (default = 'buffer://localhost:1972')
    cfg.target.dataformat    = string, default is determined automatic
