Hi, I have a trc file and I would like to cut a part of the .trc file and save it as a new .trc file in MATLAB(I'm trying to split my trials). I have already cut the data but I don't really know on how to write it back as a .trc file in MATLAB. Is there a function to do this?. I looked ad importing ...

Hi Dimitir, Sorry for the late reply. I did try weld constraint and I got the following error. What can be done to avoid this?. Is it possible to change the required tolerance level?. And another thing I face is that I am only able to weld to the physical frame hand(but in my case, it is at the wris...

Hi, I have a model where I want to add a rectangular box that is held by both the hands of the model. In order to avoid closed-kinematic chain. I have added one weld joint between right hand and the box and want to create a weld constraint to the other hand. When I try to create weld constraint betw...

I am trying to model an interaction between a human and an external box for a lifting task (Lift a cubical box with two hands together). I am using the lower full-body model (LFB model). In this model, the ground is defined at the pelvis of the model and is validated for lifting tasks already. The i...

Yes, I get it now. Thank you.

Hi Carmichael, Thank you very much for your reply. I sincerely apologise for the late reply. I had recently come across the soccer kicking model. In this model a foot ball was created as a external object and a free joint was created between the ball and the ground as a parent body. The contact forc...

Hi,

Thank you very much for your reply. I will definitely do that.

Hi Aaron, Thank you for your reply. I have also been thinking of splitting the trail into two parts of with and without box. However, I was curious to know if that is possible. I will probably wait to see if I get more responses on that. About the weld joint, I was thinking to model the left hand as...

Hi, I am trying to add a body to the model and make it a visible object to the GUI using Matlab. I got a code snippet for doing the same in OpenSim 3.3 and trying to replicate this for OpenSim4. % Create the Right Hand Sphere rightHandSphere = Body(); rightHandSphere.setName('RightHandSphere'); righ...

Hi! I am posting again because I did not get a reply last time. Please do help. I am working on the Lifting full-body (LFB) model. My objective is to add an external box to the model and model a dynamic squat lifting trial. The box should be an external object and attach to the body only during lift...
