FT_REALTIME_CTFPROXY
Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_realtime_ctfproxy”.
FT_REALTIME_CTFPROXY provides a real-time interface to the MEG data stream. This application requires Acq to stream the data to shared memory, and ctf2ft_v1 (formerly known as AcqBuffer) to be maintaining the shared memory and to prevent overruns. This MATLAB function will subsequently copy the data from shared memory to a FieldTrip buffer. 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. Since the CTF shared memory interface is only available on the acquisition machine itself, this function must run on the acquisition machine. The buffer to which the data is streamed is available through the network, so the actual analysis can be done elsewhere. Use as ft_realtime_ctfproxy(cfg) 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 To stop this realtime function, you have to press Ctrl-C See also FT_REALTIME_SIGNALPROXY, FT_REALTIME_SIGNALVIEWER
