I am following the tutorial ([Slicer Tutorial #4: Opening the PLUS Connection — Andy's Brain Book 1.0 documentation](https://andysbrainbook.readthedocs.io/en/latest/Slicer/Slicer_Short_Course/Slicer_04_OpeningPLUSConnection.html)) and have successfully exported the configuration and profile .xml files. When I click “Launch server” on PLUS Server Launcher, it prints “Connection failed, please select another device set and try again.” and throws the following errors:
|ERROR|055.036000|SERVER\> Unable to find required ProjectFile attribute in Device element in device set configuration| in :\D\PSNPb\PlusLib\src\PlusDataCollection\OptiTrack\vtkPlusOptiTrack.cxx(142)

Where is your Profile.xml located relative to the config file directory?

Both the profile and config .xml files are located in the same folder.

@Sunderlandkyl @lassoan
Would someone from your teams have sometime to help us setup the instrument via zoom session? This is very new to us, I think if we can pass the point of configuring we can make some progress, but our interns time is quite limited.

Probably the configuration files need to be in the configuration folder. Follow the pattern used in the example configuration files. @Sunderlandkyl is the expert in this - he may be able to give more specific advice.

Thanks.
@Sunderlandkyl would you have time for a zoom session?

Thanks to @Sunderlandkyl we managed to get our camera working.
We now would like to replace the generic needle model with the actual optitrack probe/stylus model. Is there a repository of 3D models? For reference , this is what we have.
