Dear Martin,
</div>
<div>
 
</div>
<div>
It seems the component cannot find the Subject. If I remember well the Subject name is case-sensitive.
</div>
<div>
Also define one single Subject. 
<span style="font-size: 9pt;">Ultimately, use the debug output to check if at least you can track independent markers positions (independently of the Subject).</span>
</div>
<div>
 
</div>
<div>
I hope it helps.
</div>
<div>
 
</div>
<div>
Regards,
</div>
<div>
 
</div>
<div>
Javier.

<br/>
<br/>
<span style="font-family: sans-serif; font-size: small;">I am working on including the Vicon component to my RoCK network of components. I run the test_vicon.rb script provided with the Vicon component but I only get NaN NaN NaN repeatedly in the output.</span>
<br/>
<br/>
<span style="font-family: sans-serif; font-size: small;">I am using a Vicon setup with 10 cameras (MX 13+ and T20) and the Vicon hubs Ultranet and Giganet. I am running the Vicon Nexus (version 1.8.5) software in a Windows PC that is connected to the hubs. This machine has an additional network card to connect to the lab network.<br/> </span>
<br/>
<span style="font-family: sans-serif; font-size: small;">I have properly provided to the RoCK execution machine the IP of the Windows PC (ping is successful) and defined the Subject and Segment that I want to track.</span>
<br/>
<br/>
<span style="font-family: sans-serif; font-size: small;">I have the feeling that I am missing something in the Vicon Nexus software environment to make it ready to provide in real-time during the test the position and orientation data of the subject that is being tracked.</span>
<br/>
<br/>
<span style="font-family: sans-serif; font-size: small;">Someone with experience using the Vicon component can point me in the right direction here?</span>
<br/>
