Hello, I have some mocap data from stop jump landing trials. I have tried to scale the model in OpenSim but because I have limited marker data I am unable to scale the body segments (pelvis, shank, and thigh) in all three directions. Therefore, my scaling setup file only includes one marker pair tha...

Thank you for your response. However, after checking the .osm file I'm not seeing the use of any of the mentioned invalid characters in the model name. I've attached a screenshot of the model name and a copy of the .osm file for convenience.

Hello, I'm trying to scale a model but every time I launch the scaling tool the solution does not converge. Furthermore, I'm not even seeing any progress in the bar that indicates the completion of the scaling. Also, after I hit run on the scaling tool I get a pop up information message, as attached...

I want to increase the strength of some muscles in the 2392 Gait Model. In order to do so, do I need to adjust the "max_isometric_force" feature in the properties window of that particular muscle? Also, how do I know how much to adjust the feature by?

Why aren't they needed? I was asking because I wanted to determine if there was a difference in the kinematic output of gait models with arms vs. gait models without arms.

Why are the arms not included on the walking gait models provided in OpenSim? Is this for simplicity reasons?
