[FieldTrip] realtime buffer does not exit

[Elizabeth Anne Bock, Ms]

Thanks for the feedback.  However, I would like to read the header and the data from the buffer into Matlab (I am doing realtime processing of the data).  Is this possible to run  the buffer in the windows environment and then read from it in Matlab?

 hdr = buffer('get_hdr', [], ft_host, ft_port)
??? Error using ==> buffer
ERROR: failed to create socket (1)

Thanks,
Beth

Hi Elizabeth,

Could you try and start the buffer from outside matlab using 'demo_buffer.exe' (to be found in the 'realtime/bin/win32' directory)? This application may operate smoother than when starting the buffer from a single matlab thread.

Best,
Arjen
