Loading Motion File to OpenSim 4.0 GUI:

[Musa Audu]

I use the following snippet of C++ code to save my state variables after an integration/simulation:

Storage statesDegrees(manager.getStateStorage());
osimModel.updSimbodyEngine().convertRadiansToDegrees(statesDegrees);
statesDegrees.print("forward_states.sto");

The resulting file saves the names of each gen coord state variable in the form:

/model_name/jointset/joint_name/gen_coord_name/value

Whenever I try to load such a file into the OpenSim 4.0 GUI I get the error message: "Could not associate motion to current model". I notice that the only way to be able to load the file is to edit it and in the header row remove all occurrences of the '/model_name'. Thus the above entry becomes:

/jointset/joint_name/gen_coord_name/value

Now the file will successfully load as a motion. Is there another way to avoid having to edit the motion file as such? Thanks.

Hi Musa,

I suspect the version of the code you're using for API development is not consistent with the code base for the GUI. At some point we had the model_name as part of the labels, but this was eliminated before the final release. Where did you get the opensim-core code base? If from github, please update and let us know if the issue persists using the latest code on master or 4.0 branch.

Best regards,

Thanks Ayman. That works. Cheers.
