Subject: [FieldTrip] real-time events in fieldtrip
 

hi everyone

I am using Fieldtrip for realtime P300 classification.
i am facing one problem that i am unable to read Events (stimulus markers from Vision recorder)

my flashing program is in Visual c, that communicates with vision recorder and markers are displayed correctly in VisionRec.
while reading from buffer i get data correctly but it doesn't gives me events.

the command

event     = read_event(cfg.dataset, 'minsample', prevSample+1);

gives me an empty vector.

I am using FT_REALTIME_BRAINAMPPROXY to read from Vision recorder.
with default setting i.e

cfg.port=51244;cfg.target.datafile      = 'buffer://localhost:1972'
cfg.target.eventfile     = 'buffer://localhost:1972'



after that if i use ft_realtime_signalviewer it displays data correctly but it shows no event.
