Hi everyone, Just let you know that I opened a pull request the latest version of ezc3d to OpenSim, which should fix the current problem. That said, if you are compiling OpenSim yourself, you can simply change the CMakeLists.txt file in the dependencies folder and bump the ezc3d version to 1.5.8. Re...

Dear all, As requested by Ayman, I've tried to open the file directly using the C3DFileAdapter using ezc3d and the file is properly loaded. As expected, it creates an empty table for the analogs when none are found, which is similar to the behavior of the previous backend (BTK). Therefore, I do not ...

Hi Ton! First, I am pleased to see this amazing improvement in loading time. The small C3D files are not long enough to load so I never had the chance to really see the difference with BTK :) I do not want to pollute the OpenSim forum, but I can still answer your question (because it is a short answ...

Dear Ton and Ayman, I have had a look at the provided file and found that the reason it fails is because Motion Analyses did not provide a calibration matrix (the parameter is present in the C3D, but is completely empty). Since I did not face this problem before, it was not taken into account in ezc...

Dear Abdullah, I am the programmer of ezc3d so I had to code all this things already to make the force platform module, so hopefully I can provide you with some insights :) The relation between Force, Moment and CoP is as follow: Moment = F ^ CoP + Tz Where, ^ is the cross product, and Tz is the [0;...

We were actually looking for a full upper limb model with muscles and hoping yours was ready already! We are looking forward trying your model.

Sweet thanks

Hi Najoua, We have just figure out how! So after loading a mot file, you have to compute spline for each coordinate, idealy filter it and then evaluate values at each time. That would look something like this : # Prepare a model model = osim.Model(model_path) state = model.initSystem() working_state...

Hello, We have the same problem, from this piece of code we get up to loading coordinate states from a file, but we can't figure out how to derivate it properly model = osim.Model(model_path) state = model.initSystem() working_state = model.updWorkingState() # Read the data data_storage = osim.Stora...

Hello! I am getting Q from a mot file produced by inverse kinematics. The values are given in degrees. I just wanted to be sure that when I populate the state using the state.setQ(Q) method [in python], it actually waits for degrees and not radian. If it waits for radian, is there a function that co...
