Re: creating IK setup file in Matlab

Hi Sheeba, I just looked into the API documentation and it looks like you might have to use OpenSim4.2 to do it. set_model_file() is only available in IMUInverseKinematicsTool for OpenSim4.1 I tested it by installing the opensim4.2 and executing the following: import org.opensim.modeling.*; my_ik = ...

Re: creating IK setup file in Matlab

Hi Sheeba

You can get the list of methods in InverseKinematicTool by using methods()

I guess you can use setModel(). Hope this helps.

Best,

Re: Extra columns with no headers in CMC generated outputs file

Hi Ayman, Hi Vishal, Since you're building/modifying models, the likely scenario is that you added state variables that have blank names or some other state variables that contain spaces in them and that causes the problem downstream. I would try to fix the problem with the names rather than the dow...

Extra columns with no headers in CMC generated outputs file

Hi, I was performing CMC on one of the models that I am developing in OpenSim. The RRA and CMC were computed without errors. While analyzing the data using MATLAB, I got the following error while executing osimTableToStruct(cmc_actuator_file_name). Unexpected number of columns in line 24. Expected =...

Re: RRA Workflow

After running RRA for several iterations the pelvic moment residuals do not seem to reduce but increase at every iteration and the values are large. Also there is drift in pelvic residuals. Hello Shivangi, I am not aware of what activity are you trying to analyze in your study. So assuming it as a ...

Re: customActuator as Pluggin - Objects not registered

Dear Ayman,

Thanks a lot! I did find the examples and it worked like a charm. Here in this case I had to build two dll files separately and load into GUI. :)

Best,

Re: Forward Dynamics with Coordinate Actuators

Thanks a lot, James! I wasn't aware of this CorrectionController at all. May I know how you wrote this setup file after adding the controller. I mean how did you know the correct names of the tags that have to be put. The API docs show member functions only https://simtk.org/api_docs/opensim/api_doc...
