thanks!

please compare the experimental marker and the virtual marker one by one to make sure that the experimental markers' name and position corresponds to the virtual marker.

Dear Prof. Uchida,

Thanks for your reply. I found how the position and acceleration are calculated. However, I found the function "get_mass_center()". It seems to get the mass center of the body. So I want to know how the function "get_mass_center()" works? What's the equation it uses?

Thanks

Dear guys.

Thanks for your reading.
I want to know how the CoM calculation of BodyKinematics works in the Analyze Tool of OpenSim 3.3? For example, what is the mathematic equation the OpenSim used?

Dear all: Thanks for reading this posting. I met two problems as follows: First of all, when I used my motion capture data to scale the model, the model happened to have some strange posture on its lower limbs. I had modified the scaled setting and the marker attachment position. However, It still h...

Hello, dear Professor and friends. I don't know how to use the .trc doc or the information in .trc to make a movie in OpenSim to show the motion of experimental human. Such movie should include the model, which could change or title with the marker changing. Currently, I can only visualize Marker T...

thanks a lot!

Yes, thanks. I have checked the related tools "Matlab_Opensim_Tools_v2" and "Lee-Son's Toolbox". However, the "Matlab_Opensim_Tools_v2" didn't have such function and "Lee-Son's Toolbox" didn't work. So could you please give me more detail about how to use them? Thanks!

Hi, Professors and Doctors. I am a freshman of the OpenSim, so hope to get some guidance. Now I meet a problem that I don't know how to convert the the *.csv docs to *.trc docs, in order to scale my model. Though there is a tool "Lee-Sonstoolbox", when I applied it to my documents, it would show no ...
