Combining BCI2000 with Fieldtrip

Post by lucamossa » 09 May 2014, 06:40

Dear community,

I'm currently trying to use FieldTripBuffer (in matlab) as the Signal Processing module for a mu rhythm application. I have no problems to read the raw signal and states but I have trouble to find a way to sent the processing result back to Bci for the classification.

I know that I must use the ft_write_event function but when I tried to use my code (with ft_write_event function) appears an error:

Error using buffer
events must be given as struct.

Error in ft_write_event
buffer('put_evt', event, host, port)

Now I think that I must define some parameters, like:

event.type=...
event.sample=...
event.offset=...
event.duration=...
event.value=...

but I don't understand which kind of value to insert in these field. Have you some hint? Did you make me some example?

Thank you very much.

Luca
