There are several possibilities. It depends on your research question. For example, after choosing a model, you can decrease the maximal isometric force in the target muscles and use static optimization to study muscle force distribution (https://opensimconfluence.atlassian.net/wiki/spaces/OpenSim/p...

Thank You. It partially solved the problem. After installing simbody and re-installing opensim I got two more errors. The first: libGL error: MESA-LOADER: failed to open iris: /usr/lib/dri/iris_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/...

Hi, I'm trying to run OpenSim with Python on Ubuntu 22.04 with no success. I installed the newest version of Anaconda, created a new environment with Python 3.11, and installed the OpenSim packages following the instructions at https://anaconda.org/opensim-org/opensim However, when I try to run the ...

Hi all, Maybe it is just a silly question. I think I'm making some confusion on understanding the CMC steps, but my question is: When I use the CMC fast target I solve for an optimization problem where the cost function is: "the sum of squared controls augmented by a set of equality constraints that...

Hi Alessandro, to solve this problem I: loaded a generic setup file: analyzeTool = AnalyzeTool(genericSetupFile); then I got the property by its index x=analyzeTool.getAnalysisSet().get(0).getPropertyByIndex(5); and with the PropertyHelper I could change the name of the file PropertyHelper.setValueS...

Hi James, It didn't work the way I was thinking. Doing the way you suggested, I could copy the IK tasks from one IKTask file to the other, but I could not modify the path name, nor even copy ( set ) the tasks, in the new Scale Setting file. It seems that I'm missing a 'set' command. Do you have any ...

Hi James,

My idea is not to use the loop, so I'll try your first suggestion and let you know if it works

thanks

Hi all, I'm trying to edit a xml file using a matlab script and I would like to know how to set the IKTaskSet file within the "Marker Set Placer" In the xml file it is: <MarkerPlacer> <apply>true</apply> <IKTaskSet file="C:\Users\Documents\Scale_Tasks.xml" /> <marker_file>marker.trc</marker_file> <t...

Hi Leo, I don't know if I understand right your problem, but you can "remove " the joint making it a "WeldJoint": http://simtk-confluence.stanford.edu:8080/display/OpenSim/OpenSim+Models#OpenSimModels-AvailableJointTypes There is this model leg6dof9musc.osim that comes with the newest version of ope...

Hi Ursula,

try to see if your markers are attached to the right segment. I think that the marker on the toe has to be attached to the calcaneus body.

hope it helps,
