<br><div><blockquote type="cite">But when you recommend me to use BrainStream is it because it contains things that fieldtrip functions cannot do or because it is just another alternative for making online experiments?<br></blockquote>No, you should be able to do everything with fieldtrip. It is indeed another alternative for making online experiments with a different approach, which I thought might be of interest to you (or in general to anyone else involved in conducting real-time (BCI) experiments), but in the end off course that's something you can only decide.</div><div>BrainStream is designed specifically for defining and executing real-time experiments and uses fieldtrips realtime buffer and hardware interfacing solutions (i.e., biosemi2ft, tmsi2ft etc.). It has all kind of built-in solutions for starting extra Matlab clients, automatic parallel execution, easy access to and switching between devices, information exchange, simulating from file or random data. In the design, you can use any Matlab code, including fieldtrip functions. However, you need to learn its specific way of defining experiments.</div><div><div><br></div><div>Kind regards</div><div>Philip</div><div><br></div><br><blockquote type="cite"><br>Regards<br><br>Hamza<br><br><div class="gmail_quote">On Wed, Apr 18, 2012 at 11:04 AM, Philip van den Broek <span dir="ltr"><<a href="mailto:p.vandenbroek@donders.ru.nl">p.vandenbroek@donders.ru.nl</a>></span> wrote:<br>

<br>
You first need to start a buffer to read the data from de biosemi device, so start the biosemi2ft, see here <a href="http://fieldtrip.fcdonders.nl/development/realtime/biosemi?s[]=biosemi2ft" target="_blank">http://fieldtrip.fcdonders.nl/development/realtime/biosemi?s[]=biosemi2ft</a>. Then if you do not change the defaults you do not need to change the cfg.dataset field for the signal viewer.<br>
<br>
There is also a signal viewer based on c code (so no extra matlab session is necessary). You can find it here: fieldtrip/realtime/utilities/viewer<br>
<br>
Best, Marianne<br>

Subject: [FieldTrip] Signal viewer + Biosemi<br>
<div><div><br>
Hello,<br>
<br>
I looked I the Signal viewer example in the following page:<br>
<a href="http://fieldtrip.fcdonders.nl/example/ft_realtime_signalviewer" target="_blank">http://fieldtrip.fcdonders.nl/example/ft_realtime_signalviewer</a><br>
<br>
I just want to know how could I view a signal coming directly from the biosemi device?<br>
(I think the following line should be changed:<br>
cfg.dataset = '<a>buffer://localhost:1972'</a>;<br>
but I don't know what to put)<br>
<br>
Thanks for your help<br>
<br>
<br>
