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

  FT_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.

  The configuration should contain              = cell-array, see FT_CHANNELSELECTION (default = 'all')
  The target to write the data to is configured as      = string, target destination for the data (default = 'buffer://localhost:1972')    = string, default is determined automatic
