IMU angular velocity to report local coordinate values?

[Junwei Sun]

When I place an IMU on the model, no matter which initial IMU orientation I chose, the IMUDataReporter gives the same results of the angular velocities for the same motion. I believe the angular velocities are global/world coordinate values. Is it possible to make IMUDataReporter report angular velocities in the local coordinate of the IMU?

I suppose it could be done with script? https://opensim-org.github.io/opensim-m ... orter.html

I would like to know how to use motion as input when running IMUDataReporter analysis with script, and how to make it report angular velocities in local coordinate of the IMU.

Any help is much appreciated!
