<br>
According to the documentation on <a href="http://fieldtrip.fcdonders.nl/development/realtime/biosemi" target="_blank">http://fieldtrip.fcdonders.nl/development/realtime/biosemi</a> the full command line is<br>
biosemi2ft <config-file> <gdf-file> <hostname> <port><br>
and "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 .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. Replacinghostname by a minus (-) tells the software to spawn its own buffer server on the given port."<br>
<br>
If you did not start buffer.exe prior to biosemi2ft.exe, you don't have a buffer server running and the error message makes sense because the buffer cannot be found.<br>
<br>
If you specify "-" as 3rd argument then biosemi2ft.exe will spawn its own buffer server in a separate thread and will connect to that. See <a href="http://fieldtrip.fcdonders.nl/development/realtime/biosemi" target="_blank">http://fieldtrip.fcdonders.nl/development/realtime/biosemi</a> and <a href="http://fieldtrip.fcdonders.nl/development/realtime/buffer" target="_blank">http://fieldtrip.fcdonders.nl/development/realtime/buffer</a>. Note that you should name the output file "ex", not "ex.gdf".<br>
