Hi, I have a problem with the Inverse Kinematics Tool. I tried to implement the Tool in a Matlab function, but I obtained this error: "InverseKinematicsTool Failed: Timestamp at row 1 with value -0.004600 is less-than/equal to timestamp at row 0 with value 0.010000 Thrown at TimeSeriesTable.h:486 in...

Thanks, Thomas. I have followed the instructions to load this OpenSim plugin, but the error "Error trying to load library MuscleForceDirection. Library not loaded " appears. Does someone know why? Also, does someone know if another way to compute 3D force in a specific marker of model exist? Thanks ...

Thanks, Thomas for the reply. I've already read all the most relevant posts in this forum, but I haven't resolved my problem. I mustn't add a force to a model, but I need to compute the 3D force generated by a single muscle, to compare it with the force calculated by MATLAB, using the EMG signals fo...

Hi, I'm trying to compute muscle forces of the MoBL-ARMS model, using Matlab, but I don't understand how to do this. I active a muscle, using FD Tool and, inside a for loop, I need to compute force for every muscle activated, supposed that this force is applied in the hand mass center. I write this ...

Using setup file created in Matlab, the FD Tool works correctly.

Thank you very much!

Hi, I'm trying to execute the Forward Dynamics Tool in Matlab, but the results obtained are wrong. I use the MoBL-ARMS model and I give a .xml file in input at FD Tool. This file contains a constant activation of Brachioradialis muscle(the other muscles of the model have a null activation). I implem...

Hi,

I'm trying to scale an OpenSim model (MoBL-ARMS) using Matlab, but when the script runs, MATLAB crashes during the command: II.processModel(myModel, path2subject).

Does someone know why?

Thanks in advance for the help,

Hi, I'm trying to scalar an 0penSim upper limb model (MoBL_ARMS) using Matlab with the characteristics of my subject. Matlab does the scaling, but the scaled model is wrong. During scaling, the model loses the ground(represented by thorax) and some bodies, in spite of they are listed in the correspo...
