Re: How to create a MOT file based on the steps of bone fracture reduction

Hello, Motion files contain the time history of coordinates. If you want a motion file to represent bone fracture reduction then you should introduce a joint into the model between the two broken bones with corresponding coordinate(s) such that you produce the motion by changing coordinate values, p...

Re: Model Open Method

Hello,

Can you specify what platform are you on, and if this issue is model specific? If so, please provide the model or a pointer/link to it.

Thank you,

Re: ConstantCurvatureJoint in next release?

Hi, Please try the 4.5 Beta release on the downloads page and let us know how it goes, as it has this built into it. Likely since the bindings you copied from 4.4 are inconsistent with the rest of the build from source, the first dll attempt fails to load but other things could go wrong in the proce...

Re: Motion Files

Hello, A motion file is just a text file on a tabular format (similar to csv but space separated) with a time column and corresponding coordinate values, an example can be found in the distribution, linked below from Tutorial 1: https://github.com/opensim-org/opensim-models/blob/master/Tutorials/Int...

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,
