Hello, I downloaded the installation file (CEINMS-0.10.0-Win32), and fixed the "Warning! PATH too long installer unable to modify PATH!". Then I attempted to check The Calibration step in the cmd window. I’ve got an error, as shown in the attached screenshot of the cmd prompt. Will this 32-bit run o...

Hi All,
I would like to know if the muscle forces that are estimated by using CEINMS are parallel to the muscle line of action for each muscle?

Thank you.

Thanks Michael for your reply.
What I understand is: the knee adduction/abduction moment, for example, is expressed in femur reference frame, is that right?

Kind regards,
Aseel

Hi All, I'm wondering about the reference point used in OpenSim inverse dynamics calculation? is it in the local body frame or global frame? According to the definition of the GRF, as shown in the attached screenshot, the force is expressed in "ground". Does this mean that the moments calculated fro...

Hi Krishnakumar,
You can use MOtoNMS "https://simtk.org/projects/motonms" to extract the emg envelope from C3D files.

Hi, As shown in the figure below, which demonstrates the laboratory and FP coordinate system. Should I define the laboratory coordinate system as: (YZX), then I have to set the motion direction as “backward”? Also for the selection of 90left OR 90right is that according to the direction of motion? G...

Thanks Jim...I'll give it a try and let you know what happens!

Hi,
How can I decompose the muscle forces into orthogonal components?
I need the component along the long axis of the femur which is contributing to the compressive KCF

I would greatly appreciated your help.

Thanks,
Aseel

Sorry I couldn't upload the figures!

Hi I’m trying to use static optimization in CEINMS, so i need to use “Hybrid mode” to construct all the muscle excitations. My questions are: 1. Do I need the calibration step? 2. In the Execution configuration file, what is the meaning of 1. <synthMTUs>, does it mean the list of predicted muscles? ...
