FT_REALTIME_COILLOCALIZER
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
