|Plug-in Gait units for forces, moments and powers in the c3d file does not match units displayed in Nexus.||Pre 2.10||Nexus displays the Plug-in Gait units as:
Plug-in Gait outputs generated by Nexus are normalized to the subject’s body mass, and their values are stored in the .c3d file as such. Therefore, the units in the .c3d file metadata should be divided by kg for these outputs (i.e. N/kg, N.mm/kg, W/kg).
Plug-in in Gait Documentation updated from Nexus 2.10 (https://docs.vicon.com/display/Nexus210/Plug-in+Gait+output+specification#PluginGaitoutputspecification-Jointkinetics)
|After completing dynamic wand wave it is possible for the Set Origin operation to fail. This is rare, but for those who experience the problem, it will be consistent.||2.10.3||The only way to get it to work again is to close Nexus down and reopen.||Solved
Resolved in Nexus 2.11.0
|Nexus performance issue when there was a large number of log messages.||2.10.1||Confirmed log workaround in Nexus 2.10.1:
Note that this will disable all log messages, both in the app and in the log file.
If you want to keep the log messages:
Resolved in Nexus 2.10.2
|GetDeviceChannel returns force plate outputs as an action force in a z-down coordinate system, compared to a reaction in a z-up system as stored in the C3D file.||2.10.1||Perform the conversion after requesting the value: rotate the force and moment outputs by 180 degrees about the y-axis, and then negate all components: this is equivalent to simply negating the y-component. This applies to both force and moment outputs.||Scheduled to be resolved|
|PC blue screen when connected digitally to Kistler force plates due to Kistler digital plug-in||2.6.1||With Nexus open:
|The Blue Trident firmware for the Capture.U app is set so that when a trial is stopped, the sensor goes into sleep mode to save power. The sensor resets the calibration in all capture modes when you stop capture.||1.2 and 1.3||None. To ensure precise calibration, we recommend that you follow the calibration procedure at the start of every trial. Instructions on how to calibrate the IMUs can be found here: https://docs.vicon.com/display/IMU/Calibrate+IMUs||Open|
|If you repeatedly enter and exit AR Visualization mode by tapping Home or exiting the app, the Capture.U app may stop.||1.1||None. If the app remains unresponsive on relaunch, restart the iOS device and flush the Bluetooth.||Open|
|Native MATLAB integration no longer supported||1.10||Native MATLAB integration has been replaced by .NET as Mathsworks support the use of .NET directly in MATLAB (https://uk.mathworks.com/help/matlab/using-net-libraries-in-matlab.html). To make use of Datastream SDK 1.10, update legacy MATLAB scripts to .NET. To continue using native MATLAB integration, refer to support in Datastream SDK 1.9.||Solved|
