Hello! I am new to MOCO so perhaps my problem is obvious. I am tracking markers only (no GRFs) of some of my own data (trials + model), following the exampleMarkerTracking10DOF.m example. However, there seems to be an issue with tracking longer files. I have some trials which are ~12 seconds long an...

Hello Are there any known issues with the plot function in opensim 4.3? I'm trying to plot moment arms against joint angle, but there's a few issues: 1. If I move any aspect of the LoA (insertion, via point, wrapping surface etc) and then replot the moment arm, it will not plot. I get an error telli...

I have a lower limb model in Opensim 4x (have an earlier 3.3 version too if need to revert). My pelvis has z up rather than y up*. Can I use the TransformAxis function in the matlab API to correct this? If so, can someone please explain how it works? I've looked through the doxygen page but I'm lost...

Thanks for the help, Thomas! As an update, I ran forward dynamics in opensim with all joints apart from pelvis_ty locked. I placed the model above the ground plane and let gravity pull it down. The model successfully bounced on the ground plane, indicating that my contact spheres and ground plane ha...

aaaah! I thought it was a problem with the DOF name.

My model was setup with the centre of the pelvis at location 0,0,0 so I set the default value of pelvis_ty to be 'standing' on the ground. But I assume this might be the issue then! I'll investigate that issue. Thanks for the advice!

I am trying to replicate Tutorial 1 using my own data. I have a 4x opensim model, a .zml file and a scenario, following the setup for Tutorial 1. I have changed all DOF names to match those in my own model. However, I am getting a bizarre error when loading in the model: SCONE version 2.0.0.2243 RC ...

Hello Thomas Thank you so much for such a quick reply! Woops, I was only looking at the Tutorials folder, not the example! I see it now. Thanks! I now get a new error telling me that it cannot find my model. When I changed my directories, I went to Tools>Preferences and then changed the scenario loc...

Hello! Just getting started with SCONE so have a very basic question. How can I read in opensim 4x versions in the latest SCONE? I've tried a few varieties of what I think the code might be, but with no luck! So far I have the following: # Model used in simulation Model{ Model= Human_model_SCONE.osi...

Thank you, Ayman

I've submitted a bug report just now with the data. Hopefully someone can help

I'm unable to get to the scale popup at all. As soon as I use the drop down menu to open up the scaling tool, it crashes.

I have a human lower limb model with muscles, contact spheres and a markerset. I'm using versions 4x (have tried 4.3 and 4.2 - same issue in both). Every time I go to Tools > Scale Model, opensim will crash (I don't get any further than clicking on 'scale model' in the drop down menu). It doesn't do...
