                    <p>Dear Sophie and Hamza,</p>
                    <p>The connection between the Biosemi Active2 system
                      and the FieldTrip buffer is handled by interfacing
                      software biosemi2ft (part of fieldtrip), and
                      should be started from the terminal (mac) or
                      command prompt (windows).</p>
                    <p>
                      The interfacing software is located in the
                      FieldTrip folder:
                      ../fieldtrip/realtime/acquisition/biosemi/biosemi2ft</p>
                    <p>
                      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 streamed and/or recorded, and
                      whether the data should be downsampled. For more
                      information about configuration files for
                      different acquisition systems, see the <a
                        moz-do-not-send="true"
                        href="http://fieldtrip.fcdonders.nl/development/realtime/biosemi"
                        target="_top">Fieldtrip website</a>.</p>
                    <p>
                      To start the buffer that connects to the Biosemi
                      Active2, open the terminal (Mac) or command prompt
                      (PC) and in the folder where you would like to
                      save your data execute (change path according to
                      your system and location of fieldtrip toolbox):
                    </p>
                    <pre>../fieldtrip/realtime/acquisition/biosemi/biosemi2ft <config_file> <gdf-file> <hostname> <port>

<config_file>: configuration file
<gdf-file>: base name of the gdf file. The suffix .gdf and session counters will be added automatically.
<hostname>: optional, default is 'localhost', specify '-' to spawn a local buffer (recommended) 
<port>: optional, default is 1972</pre>

                  <div>
                    <p>Note that the manually specified name of the file

                      myfile.gdf doesn't exist.</p>
                    <div>Once this is running, you get access to the
                      data through the fieldtrip buffer filled with data
                      by biosemi2ft, i.e., fieldtrip fileio functions
                      give you access to the data:</div>
                    <div>ft_read_header('<a moz-do-not-send="true"
                        href="buffer://localhost:1972%27">buffer://localhost:1972'</a>),
                      or</div>
                    <div>ft_read_data('<a moz-do-not-send="true"
                        href="buffer://localhost:1972%27,%27begsample%27,1,%27endsample%27,100">buffer://localhost:1972','begsample',1,'endsample',100</a>,........</div>
                    <div>For further information, see fieldtrip website.</div>
                    <p>(more info on how we use the system at our
                      department can be found here: <a

                    <p>Hope this helps you to get things running in your
                      place. If you have any further questions, just let
