<div class="gmail_extra">Dear Boris<br><br>Due to my misunderstanding I thought the realtime processing is done by reading the data from a gdf file that is created by the biosemi2ft function.<br>Reading the signal viewer discription on your site made me understand the realtime processing and reading from a buffter.<br>

Could you perhaps elaborate on your question? I was also under the<br>
impression that you asked how to view the (real time) Biosemi signals<br>
--- which Marianne explained. What are you trying to achieve, what is<br>
your approach, and on what aspect are you asking for help?<br>
<br>
Best,<br>
