Re: Converting MVNX quaternions to .STO file
Thank you so much for your help. It resolved my issue and I am sharing the code below in case someone needs it: fid = fopen('../Experimental_Data/OpenSim_IMU_Dataset.sto','w+'); fprintf(fid,'DataRate=240.000000\nDataType=Quaternion\nversion=3\nOpenSimVersion=4.3\nendheader\n'); fprintf(fid,'time\t%s...

Re: Converting MVNX quaternions to .STO file
Thank you so much for your reply. I have already checked the example file. I am using MVN instead of the MT system, which already gives the sensors' orientation as quaternions instead of raw sensors' orientation/acceleration data. Therefore, "IMUDataConversion.m" does not work for my system. My ques...

Converting MVNX quaternions to .STO file
Dear OpenSim Community, I am using the MVN link and MVN analyzer system to record the motion data. This system directly provides the orientation of sensors as a .XLSX file. My problem is with converting the data to the format required by OpenSim .STO: - MVN Analyzer provides all data in MVNX format ...

Creating a Custom Actuator in OpenSim
Dear Opensim experts, We have a dynamic model of an actuator (+ mechanism) and we want to implement this actuator in the OpenSim environment to be used in the musculoskeletal model. I would be very grateful if you could guide me about how we can construct our specific actuator with its own dynamics ...

Jacobian between two joints
Dear OpenSim Experts, I assigned an actuator to the torso and now want to get its torque profile in another frame. I would be grateful if you could help me with the following issue: Is any specific command in OpenSim API to do this transformation? If there is no such command, is it possible to get t...

AnalyzeTool Error
Dear Opensim Experts, I am trying to run analyzetool using Matlab. In some cases, I am encountering the following error which I could not figure out its reason. According to the message, states.sto file is not matching with the model states but I did not make any changes on the state files. It would...

Re: Scaling Geometry, Weight and Inertia of a New added Body
Thanks, Dr. stanev for your kind helps and patience,
I will discuss about the alternatives with my professor to find a way to move forward.
Sincerely,
Ali.

Re: Scaling Geometry, Weight and Inertia of a New added Body
Thanks again for your reply,
So, do you recommend to not model the bodies of exoskeleton with inertial properties and perform ideal exoskeleton cases similar to their work?

Re: Scaling Geometry, Weight and Inertia of a New added Body
Thanks for your reply Dr. Stanev, I am trying to use the Loaded walking model and data https://simtk.org/projects/assistloadwalk . My aim is to model some exoskeletons that we have designed on this model with all inertia and masses to perform the simulations. 1) I am adding bodies to the previously ...
