OpenSense (Working with IMU Placer)

I am trying to work with OpenSense, and would like to know if we can modify the position of IMUs for the calibrated model generated using IMU Placer. I tried to read OpenSim documentation for IMU placer but couldn't find or maybe understand any topic pointing toward this. Please suggest how could mo...

Re: .mat to .mot file for use in object to inverse kinematics plugin

Sir, I have one more question regarding the Reference Frame for the Orientation Quaternions used as input in OpenSense. Whether the orientations have to be in Local Reference Frame (NED) or Device Reference Frame(Like in phone; positive y along the portrait side, z pointing downward away from the sc...

.mat to .mot file for use in object to inverse kinematics plugin

I am using a basic MPU9250 IMU for my project and the data generated through this is saved in CSV format. I have generated the quaternions after filtering the IMU data using MATLAB and stored them in .mat file as N*4 matrix. Now, I want to generate the .mot file for further use in object to inverse ...

Re: File Converter for IMU (OpenSense)

Thank you for the reply. Yes I have got the quaternions at each time. It would be really helpful if you could share the the code or approach to convert the quaternion/rotation matrices to SimTK rotation object.
