Hi Patrick and Shadi

Aat the Donders Centre in Nijmegen (Netherlands) we are developing  
and using FieldTrip (our matlab toolbox) for realtime processing of  
EEG and MEG datab. We already had success for classifying 275 channel  
MEG data online in Matlab in a imaginary movement paradigm to control  
a robot arm. Furthermore, we have implemented an interface for a  
Brainamp amplifier. Support for other amplifiers is relatively easy  
to add and we will do that in the future (biosemi is certainly on our  
to do list). Another possibility is to use BCI2000, which also allows  
you to do part of the processing in Matlab. We are working together  
with Gerwin Schalk (BCI2000) on the matlab ascpects and hope to be  
sharing code and ideas in the near future between the BCI2000 and  
FieldTrip projects.

The fieldtrip toolbox is of course already being used for some  
aspects in EEGLAB (notably dipole fitting). I can imagine that you  
would find it relatively easy to use our Matlab realtime reading  
functions together with functions from EEGLAB. The fieldtrip reading  
functions and event/trigger handling is very similar to the EEGLAB  
functions.

Sofar we have not yet released the real-time components of the  
FieldTrip toolbox in the public release version, only to a few close  
collaborators. Once the code is sufficiently stable and mature, we  
will release it under the GLP as part of our toolbox. That may take  
another 6 months or so. If you are interested in already trying out  
matlab functions for realtime access to EEG data, please contact me  
outside of the EEGLAB mailing list to discuss further details.

best regards,
Robert
