Dear all,

I tried to use SliceIGT and PLUS (PlusApp-2.9.0.20190802-Win64) in combination with Optitrack Prime 13 cameras (Motive version 2.0.0). To design the configuration file I have followed this guide:  
[http://perk-software.cs.queensu.ca/plus/doc/nightly/user/DeviceOptiTrack.html](http://perk-software.cs.queensu.ca/plus/doc/nightly/user/DeviceOptiTrack.html)

So I have stored a .xml config file as well as two RigidBodyFiles.

According to the log files, the server started successfully, still two warning and one error occured:

|INFO|025.010000|SERVER\> Server status: Starting servers.  
|WARNING|025.011000|SERVER\> Buffer item is not in the buffer (Uid: 0)!| in E:\D\PTNP64b\PlusLib\src\PlusDataCollection\vtkPlusTimestampedCircularBuffer.cxx(176)  
|WARNING|025.045000|SERVER\> Unable to get timestamp from OptiTrackReferenceToTracker tool tracker buffer for time: 0| in E:\D\PTNP64b\PlusLib\src\PlusDataCollection\vtkPlusChannel.cxx(1293)  
|ERROR|025.046000|SERVER\> Failed to get tracker buffer item UID from time: 1.137856| in E:\D\PTNP64b\PlusLib\src\PlusDataCollection\vtkPlusChannel.cxx(1325)  
|INFO|025.075000|SERVER\> Plus OpenIGTLink server listening on IPs: 169.254.62.161, 169.254.75.70, 169.254.44.54, 192.168.132.1, 192.168.47.1, 192.168.5.37, 169.254.35.96, 192.168.56.1, 127.0.0.1, 169.254.119.51 – port 18944  
|INFO|025.076000|SERVER\> Server status: Server(s) are running.

When connecting to the server in Slicer 3D (v4.10.2) the following warning appears:  
|WARNING|181.934000|SERVER\> Buffer item is not in the buffer (Uid: 1)!| in E:\D\PTNP64b\PlusLib\src\PlusDataCollection\vtkPlusTimestampedCircularBuffer.cxx(182)  
|WARNING|181.936000|SERVER\> Unable to get timestamp from default tool tracker buffer| in E:\D\PTNP64b\PlusLib\src\PlusDataCollection\vtkPlusChannel.cxx(1158)

Furthermore, in IGT/PlusRemote I cannot select a ‘Capture device ID’ and a ‘Reconstructor device ID’ in the dropdown list (it is empty).

Does anyone know these warnings/errors? And does anyone know if PLUS is compatible with the Optitrack Prime13 or just with Duo/Trio?

Best,  
Bernhard

Yes, Plus toolkit supports all Optitrack cameras. Since most likely the issue is in the Plus configuration file, let’s continue the discussion here: [https://github.com/PlusToolkit/PlusLib/issues/580](https://github.com/PlusToolkit/PlusLib/issues/580)

Thanks, this issue is fixed.
