Muscle path issue - MOBL_ARMS_41
Hello, everyone. I ran into a issue with the LAT muscles in the MOBL_ARMS_41 base model. It seems that the muscle insertion points are lost and extend beyond the bones for some shoulder_elv and elv_angle values. Here are some combinations in which I found the muscles have the issue: shoulder_elv at ...

Re: Change in Muscle Geometry Path Calculations post-4.1 (Mobl-Arms models affected)
Hi Maximillian, thank you for your reply.
I finally got to post a reply.
I did the plots you suggested.
I do see a spike, sharper when plotting the base model (not scaled).
I attached the files you asked for.
Thank you for the help!

Re: Change in Muscle Geometry Path Calculations post-4.1 (Mobl-Arms models affected)
Hi Maximillian, I'm using the model Mobl-arm in OpenSim 4.1. I ran the IK tool with experimental data. I got a estrange behavior in one of the muscles (LAT1) it seems it loses its point of origin or insertion at two time instants, I want to know if you could give me a hint about how to verify if tha...

Re: disarticulation of bones after scaling MOBL_ARMS_41
Hello, I didn't know if I should open a new topic or not, I would like to know if the muscle actually changed its origin point or is it a visualization issue? I applied the IK tool to the scaled model, and at two time instants the LAT1 muscle apparently changes its origin point. How can I check if i...

Re: disarticulation of bones after scaling MOBL_ARMS_41
Hello Ayman, thanks for the help.
I did what you suggested, I saved the scaled model in the same folder as the unscaled model and reloaded it and it displayed just fine.
I appreciate your quick response!

disarticulation of bones after scaling MOBL_ARMS_41
Hello, I'm using OpenSim 4.1. The model is the MOBL_ARMS_41.osim I have added some markers to the humerus, forearm and hand. I checked that the new markers were on the correct parent. I also set the model to 0 in the coordinates related to the thorax (translational and rotational). I set the trc fil...

Re: How to get Moment Arm of a Body on Matlab ?
Hello Sepehr,
Can you mention what files did you use as input for the moment arm calculation, please?
Thank you so much in advance.

Re: Error trying to run SO
Update.
I did not get any exception anymore, after correcting the paths in the External loads files. I don't know why I got the second exception mentioned in this post, and then it did not appear anymore. I was able to run the SO tool. Thanks for the help.

Re: Get muscle fiber lenghts used in static optimization
Hello, I'm trying to use the muscle analysis option in the analysis tool, but I did not find information on how to use it. The OpenSim documentation shows how to use the analysis tool in general, and then the induced acceleration analysis and probes. What I want to verify if the muscle lenght of som...

Re: Error trying to run SO
Ayman Habib, thank you so much for your answer. I checked the ExternalLoads file as you indicated and the path for data_source_name was incorrect, I'm sorry, I thought I had checked everything before writing the post. I modified it and I was able to run the OS though I got a different exception: ___...
