[FieldTrip] Having troubles with Emotiv + Fieldtrip + Matlab

[Lilla.Magyari at mpi.nl]

Hello Ricardo,

I haven't tried to work with Emotiv, but I see an FtBuffer.h file in the
latest version of FieldTrip in the  realtime/src/buffer/cpp. I hope this
helps.

(It is also not clear for me if you downloaded only files related to
emotive, or also the whole FieldTrip package (this latest is probably
useful)).

Best,
Lilla
