Ok I got it.
Thanks.

Hello Happy new year to everyone! I'm trying to open "Multiple Speed Walking Simulations" models and run some extra analyses in my OpenSim 3.3 but the models does not open correctly and GUI and coordinates window remain empty. I tried to load associated motions in the mentioned simulation package bu...

Hi Xijin
you may change "Muscle Display Radius" in the "Preferences" window under "Edit" tab on the top left corner of GUI.
Hope it works for you,
Best.

Hey guys,

I'm a student learning OpenSim, here's my question:
Why do I have activation values in the results file when I run Forward dynamic tool with no controls input.

FYI, I'm running Leg6dof9musc model.

Best.

Thank you Dimitar for your great reply. Can we also address the "lack of MOCAP data problem" with motion files shared by the community? I another words, consider our patient as Subject_A and we want to use Subject_B motion file to run Inverse dynamics tool for subject_A implementing these two files:...

In order to study bone fracture in patients with osteoporosis, I need patient's exact muscle forces magnitude, location and direction (as FEA boundry conditions), while it is difficult to get such subjects to a MOCAP lab and get their data. 1. Is it possible to get a body-matched subject perform our...

Hi I'm trying to do "Tutorial 3 - Scaling, Inverse Kinematics, and Inverse". I got scale results below, that seems satisfactory: total squared error = 0.0137265, marker error: RMS=0.0187606, max=0.036696 (R.Thigh.Upper) but when running IK tool I get the results below: total squared error = 0.013286...

Thank you Thomas.

Thanks for your reply and I add something for future refrence .osim files may not have a marker set at first and <Markerset> tag would be empty, but once the get scaled an appropriate marker set would be added to the scaled.osim file and this can be used be IK tool. Creating/Editing marker sets are ...

Hi Reading Scale Tool doc. I didn't get this tip: Scale Tool>>Getting Started with Scaling>>Evaluating your Results>> "5. a.Again, avoid adjusting the positions of the landmark and FJC virtual markers to match the experimental markers." 1. As I realised, you change virtual markers positions and prev...
