[FieldTrip] Signal viewer + Biosemi

Wed Apr 18 12:10:54 CEST 2012

Hi Hamza,

> But when you recommend me to use BrainStream is it because it contains things that fieldtrip functions cannot do or because it is just another alternative for making online experiments?
No, you should be able to do everything with fieldtrip. It is indeed another alternative for making online experiments with a different approach, which I thought might be of interest to you (or in general to anyone else involved in conducting real-time (BCI) experiments), but in the end off course that's something you can only decide.
BrainStream is designed specifically for defining and executing real-time experiments and uses fieldtrips realtime buffer and hardware interfacing solutions (i.e., biosemi2ft, tmsi2ft etc.). It has all kind of built-in solutions for starting extra Matlab clients, automatic parallel execution, easy access to and switching between devices, information exchange, simulating from file or random data. In the design, you can use any Matlab code, including fieldtrip functions. However, you need to learn its specific way of defining experiments.

Kind regards
Philip

Might you be interested in BrainStream, the code can be downloaded from (http://code.google.com/p/brainstream/).
