Nevermind the second post. The GRF showed up in the visualizer, but it took a while. The GRF data seems to be appearing fine now just really slow and choppy compared to v3.3

The marker data still is not showing up at all.

Out of curiosity I have also tried previewing GRF data in the visualizer and have had no luck with that either.

Hello, I have been trying to use the Preview Experimental Data feature with the Preview Static Pose feature of the Scale tool to evaluate my scaling results but haven't gotten it to work in OpenSim 4.0. The blue experimental markers aren't showing up in the visualizer even though all of the marker o...

Thanks for the reply Josh!
I meant to send a post here mentioning that I had found that out while running Inverse Kinematics on a person turning around. I have since fixed this in my models so that they are able to move more freely.

Thanks! That should do.

Hello, Is there any way to get more detailed error reports for the scaling and Inverse Kinematics tools? The message console returns the total squared error, the RMS error, and the max error, but is there any way to get the errors for other individual markers? I have looked at the User's Guide docum...

Update: By locking the scaled model's subtalar and mtp angle I was able to get the IK to run completely. I am still not completely sure why the generic model works without the locking. I would also still like to know any other tips anyone has about this issue that may help me out more. Thanks, Adam ...

I tried to include the model and geometry but it made the file to large. I have been using the Upper and Lower Body model based on Delp et al. and Holzbaur et al. A link is here to download it and the associated geometry files.

Hello, I have been trying to run inverse kinematics on my scaled version of a model and it will not work. Oddly enough when the model is not scaled the inverse kinematics study runs but has large marker position errors. The error message I receive when I run IK with the scaled model is always this (...

I collected data again with the same subject. This time I experimented by having him stand facing the positive direction and the negative direction. I found that if I have him face the positive direction the pelvis will not rotate but if he faces the negative direction the pelvis will rotate. I didn...
