Hi guys,

I just downloaded OpenSim 4.0 to play a bit with the Operational-Space Controller shown in the following link:

https://simtk-confluence.stanford.edu/d ... I+Tutorial

Before I can even try it out, I receive the error message

Object: Cannot not open file C:\Users\XXXXXDocuments\OpenSim\4.0-2018-08-27-ae111a49\Models\Leg6Dof9Musc\leg6dof9musc.osim.
It may not exist or you do not have permission to read it.
Thrown at object.cpp:104 in Object().

when I want to open the model. (Via File - Open Model)

This also occurs when trying to open other (pre installed) OpenSim models.

Can anyone help me regarding this issue?
Did I forget to install a certain add-on for generally running models in OpenSim?

Thank you guys!

Hi,

Probably the provided path for the model is incorrect. If you are interested in the operational task space you can also find the following implementation

Hello,

It's also possible that the path used to install OpenSim Resources (models) has non ASCII character which would be the case if user name is has non ASCII characters, please try to copy the Models folder somewhere else (e.g. C:/OpenSimModels) and retry.

Please let us know how that goes,
