Re: Cannot post long question
My first suggestions is not to post a long question. People volunteer to answer questions and that takes time-- time that is in short supply. Long questions take a long time to read, think about, and formulate a response. You are less likely to get an answer if you ask such a question. Keep question...
Re: .mot file
You can leverage the Matlab Structs() and a conversion function to build your own motion files. Below is a simple example of defining a motion for a single time for three model coordinates. You can update easily by defining an array of coordinate values for each of the coordinates in your model. Goo...

Re: Error importing APDM data
Hi, Kevin-
The IMU tracking methods, including all the fixes, have been rolled into the upcoming OpenSim 4.1 release. The Beta release is almost ready to send out and I can ping you when it is ready to get tested if you would like to try it out?

Re: coordinate system of the sensors
This is not a body, it is a WrapObject. The behavior of the wrap object seems to be what it is designed for so I am not sure what the problem is?Further, the tibia_r body knode BF_ at gastroc_r shows only a half body (half cylinder) with a single y-part. Maybe this is a bug.

Re: Markers can't follow the motion
It is hard from the picture to know what the behavior of the model marker R_Frame_upper is. What do you mean by 'markers can't follow the motion of the external parts'? Do the model markers stay in a single global location during an inverse kinematics simulation? Or does the marker move with the mod...

Re: OpenSim 4 0 on Mac no Examples and Default Models
When you open the 4.0 GUI for the first time, it asks you where you want to install the resource folder. If you missed that, or not sure where you specified, you can for the GUI to re-ask you by typing installResources() in the GUI scripting shell window.

Re: coordinate system of the sensors
Hi, Henrike-
We have been working on fixes to the bugs and they will be included in the soon-to-be-released OpenSim 4.1 beta. We can include you in the beta testing group if you would like to test the fixes?
Cheers,

Re: CMC - Muscle and tendon Stiffness
It may be useful to investigate the fiber lengths and velocities-- perhaps the fiber velocity is such that the muscle cannot generate hardly any force so the optimizer preferentially uses other actuators.
