BrainStream does not connect to the hardware directly, but via a [http://fieldtrip.fcdonders.nl/development/realtime/bufferFieldTripBuffer FieldTrip buffer]{{Dead link}}. The connection between hardware systems and the FieldTrip buffer is handled by interfacing software. Here, we will show how to use the interfacing software for the BioSemi acquisition system (biosemi2ft). For more information about the interfacing software for other acquisition systems, see the [http://fieldtrip.fcdonders.nl/development/realtimeFieldTripWebsite FieldTrip website]{{Dead link}}. | ||
In BrainStream, the interfacing software is located in the FieldTrip folder: fieldtrip/realtime/acquisition/<system> (you can find the FieldTrip folder by typing <tt>bs_folder('FIELDTRIP')</tt> in the Matlab command window). Copy this folder to the location where you want to execute biosemi2ft (note that the recorded data will be saved in this location as well). | In BrainStream, the interfacing software is located in the FieldTrip folder: fieldtrip/realtime/acquisition/<system> (you can find the FieldTrip folder by typing <tt>bs_folder('FIELDTRIP')</tt> in the Matlab command window).

The BioSemi system needs a configuration (.cfg) file in which some acquisition-related settings are specified. Configuration files for the BioSemi system specify for example from how many channels data should be recorded, and whether the data should be downsampled. Several configuration files for the BioSemi system are available in BrainStream's resources folder (type <tt>bs_folder('RESOURCES')</tt> in the Matlab command window to find this folder).
