After you've downloaded data from Vicon IMUs, you can delete the data in Nexus so that the IMUs are ready for re-use.

In addition, if you have erased data from an IMU sensor using Capture.U Desktop or IMeasureU Step, you can update the information displayed on the IMeasureU tab in Nexus so that it does not display the erased data.
