The following issues are known to exist in this release of Vicon Nexus.
|A crash can occur if any Noraxon EMG error messages are not dismissed before shutting down Nexus.||Dismiss all Noraxon EMG error messages before exiting Nexus.|
|The Load Trial command in the Python SDK is not able to load a trial.||Run the Python script from IDE or command line.|
Some of the latest versions of the FFDShow video encoder fail to work properly.
Vicon recommends the use of ffdshow_rev3562_20100907.
|Vue video 3D overlay shows a small offset when calibrated in 1080p but displayed in 720p||Vue video cameras should be calibrated in the same video mode at which data is to be recorded.|
|If a system contains legacy Vicon MX Controls with two ADCs, the second ADC is not read/recognized by Nexus.||Contact Vicon Support.|
Running a legacy VPI operation removes non-standard model outputs.
Use the equivalent native operations.
AMTI digital device plugins missing required dependencies.

Basler cameras do not work under Windows 10 with Pylon drivers earlier than Pylon5.
If Basler cameras will be connected to Nexus 2.5, update to the Basler Pylon5 SDK and drivers (v5.0.0), which are available from the Vicon website.
Cometa/Aurion ZeroWire/Wave do not work under Windows 10.
Device drivers are not available for Windows 10. Use Windows 7 instead.
When the system frame rate is set above 80Hz, if you enable Preview mode, no preview is displayed for Vicon Vantage cameras (the Camera view is blank).
To use Preview mode with Vantage cameras, select a system frame rate below 80Hz.
When you right-click the Devices node on the System Resources pane, Noraxon is not available in the Add Digital Device menu.
When you install the Noraxon plug-in (ViconInterfaceForNoraxon - v18.104.22.168.msi), change the installation path to C:\Users\Public\Documents\Vicon\Nexus2.x\DigitalDevices\
.NET is turned off by default on Microsoft Windows 8, which stops ProEclipse running.
Enable .NET framework 3.5 on Windows 8 machines. To do this, open the Control Panel, click Programs and then click Programs and Features. Click Turn Windows features on or off and select the Microsoft .NET Framework 3.5.1 check the box. You can do this before or after installing Nexus.
MATLAB/Nexus integration will not operate on Windows 7 unless the .NET framework 4.5 is installed. Attempting to run MATLAB pipeline operations reports:
Error Run MatLab Operation
Install .NET framework 4.5 from.
Noraxon Telymyo DTS device halts camera and analog data delivery when Noraxon devices are housed/not charged.
Digital devices now have an Enabled parameter in their Properties pane. To prevent a given manufacturer's plugin from holding up the rest of Nexus, clear Enabled for ALL devices from that manufacturer.
Unable to run legacy Static Gait Model under Japanese Windows.
Log entry reads:
No parameter file found
The legacy Plug in Gait model does not support international character sets. Instead of using the legacy Plug-in Gait model, use the native Nexus 2 replacement gait model (found under Data Processing pipeline operations: Process Static Plug-in Gait Model and Process Dynamic Plug-in Gait Model).
Export c3d at the end of a pipeline does not clear the trial and leaves the trial with a dirty flag (*).
The Export C3D operation does not write out the subjects associated with the trial. To remove the dirty flag on a trial, save the entire trial, which saves all associated files (x2d, xcp, etc), using the Save Trial - C3D + VSK operation.
Video capture duration can be limited directly after deletion from SSD storage.
After deleting your video files, wait a few seconds before starting your next capture. This is because some Solid State Drives require a few seconds to recover full Write speed after file deletion.
Spaces in variable names can cause BodyLanguage to fail.
When creating subject parameters for use in BodyLanguage modeling, use underscores instead of spaces.
Nexus can suffer many problems if Eclipse databases are created in locations that are Read-only. These problems range from data silently failing to save to crashes.
NEVER create Eclipse databases in locations that require administrator privileges to read or write.
Starting a capture very soon after a change to the system frame rate, or a resynchronization, can result in erratic capture behavior (failure or dropped frames).
Avoid starting captures soon after changing the hardware setup.
PAL or NTSC camcorders are included in Active Wand camera calibration if the MX system is set to run at the same standard (i.e. PAL or NTSC).
Before performing active wand camera calibration, disable the camcorders.
