-The acquisition setup consists of a battery box, the AD box, an analog input box, and the USB receiver device. ​ We provide a standalone tool called **biosemi2ft** (see ''​realtime/​bin/​&lt;your OS&gt;''​) that interfaces directly to the USB driver and thus does not depend on the Actiview software that Biosemi ships. We have tested the tool on Windows XP (32 bit), Windows (64 bit), Mac OS X (32 bit), and Linux (32 bit).  It is called on the command line like this:+The acquisition setup consists of a battery box, the AD box, an analog input box, and the USB receiver device. ​ We provide a standalone tool called **biosemi2ft** (see ''​realtime/​bin/​<your OS>''​) that interfaces directly to the USB driver and thus does not depend on the Actiview software that Biosemi ships.

 The first argument must be the name of a configuration file (see below). The second argument determines the base name of a GDF file that data is written to. The suffix ''​.gdf''​ will be added automatically,​ as well as session counters (see below) and additional file name parts ''​_1'',​ ''​_2''​ and so on for splitting the data over multiple files (to avoid 2 GB limits). The optional third and fourth argument are the hostname and port of the FieldTrip buffer. Defaults are ''​localhost''​ and ''​1972''​. Replacing ''​hostname''​ by a minus (-) tells the software to spawn its own buffer server on the given port. The first argument must be the name of a configuration file (see below).
