FT_REALTIME_SIGNALVIEWER

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

  FT_REALTIME_SIGNALVIEWER is an example realtime application for online viewing of
  the data. It should work both for EEG and MEG.
 
  Use as
    ft_realtime_signalviewer(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 = 'all')
    cfg.jumptoeof  = whether to skip to the end of the stream/file at startup (default = 'yes')
    cfg.bufferdata = whether to start on the 'first or 'last' data that is available (default = 'first')
    cfg.readevent  = whether or not to copy events (default = 'no')
    cfg.demean     = 'no' or 'yes', whether to apply baseline correction (default = 'yes')
 
  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 realtime
  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 RT 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
