[FieldTrip] Problem with retrieving the data and events in fieldtrip RDA interface of Brainvision recorder

Hello all,

I'm trying to stream EEG-data from Brainvision recorder software into the fieltrip buffer. While the data is transferred, the events are not transferred at all.

I'm using "ft_realtime_brainampproxy.m" I noticed two things in the script:

1. Line 195 states 'Should I apply the calibration here?'

What does this mean? Does this create a problem in retrieving the data? The data in the field trip buffer does not have the same range as in the recorder software.

2. Line 198-200. Here the events are not stored in the event-structure. So this is why the events are not transferred.

Has anyone noticed the same problem? How did you implement the event structure?

Thanks in advance.

Kind regards,
