Re: Installation Problems (Open Sim 4.4)

Hello, The instruction page refers to folder " C:/Users/<username>/Documents/OpenSim/4.0/Code/Matlab", however there're some variations depending on your installation: 1. 4.0 likely will change to 4.x dependent on the version installed. 2. Your admin (if not your personal computer) can install the r...

Re: Model customization

Hi Guido, Built into the mesh files are some assumptions: 1. Units: looking at the mesh alone is not enough, it's rather how it's scaled relative to the rest of the model. 2. CS: coordinate system and origin location I'd recommend you look at a version of the model that display correctly and make su...

Re: FullBodyModel ribcage missing

Hi Malin, Earlier versions of OpenSim (pre 4.0) were using code that was capable of reading binary vtp files, since we moved to 4.0 we switched to our own parsers that can only handle ascii vtp files. In most recent distributions (including 4.4) we distribute an ascii version of the same file. Assum...

Re: Message

Hello, If the file in question exists indeed and you can open it (for example to edit/inspect external loads) then it's possible the issue has to do with the use of absolute paths to locate the external loads file and/or data file(s) contained within them. Try to get all the files in one folder and ...

Re: Limb swapped between vicon and opensim

Hello,

You should check for consistent naming of the markers between all the data sources since the association is based on names and we have no way to see what the names in vicon or the model you're using are.

Hope this helps,

Re: Unable to load motions into models

Hello Raghavi, Let me explain why you may get such a message. Motion files are basically csv like text files that contain trajectories of model coordinates over time. If you try to load a motion to a model that doesn't have these coordinates (based on name matching of the file header) then you'll ge...

Re: How to do Kinematics with IMU data workflow in Python

Hello, Just guessing here that the function expects a reference to string, and that fails because the argument is created on the call line. I'd split the last line into two: full_file_name = .... osim.STOFileAdapterQuaternion.write(quaternionTable, full_file_name ) Please let us know if that works, ...

Re: Installing OpenSim 4.0 on MacOSX

Hello,

I'd try version 4.4 on your machine and see if the same problem exists or if it works, this should help resolve if the OS is the issue.

Please let us know what you find out,

Re: Unable to find body geometries

Hello, The vtp files are included in the distribution e.g. if the application is installed into D:\OpenSim 4.4, they would be under D:\OpenSim 4.4\Geometry. Under the Edit->Preferences menu of the application there is an entry for "Geometry Search Path" that should point to this folder "D:\OpenSim 4...
