Thanks so much. Once I set the x-offset for the scaled model to zero this addressed question #2.

Hi, I am trying the scaling tutorial using the gait2354.osim model: https://simtk-confluence.stanford.edu:8443/display/OpenSim/Tutorial+3+-+Scaling%2C+Inverse+Kinematics%2C+and+Inverse+Dynamics I followed the instructions for scaling and the model scaled w/out error. I have attached an image of the ...

Thank you!!

Greetings, I get the following error message when trying to view (Preview experimental data) my trc file: A java.lang.ArrayIndexOutOfBoundsException exception has occurred. Based on a prior post regarding the same out of bounds error, I did shorten my file name to 14 characters (down from 21 charact...

James, Thanks for your response. I do understand that "... you have to provide weights for scale and IK." But is this true for the scale factors as well? This is the 2nd tab in the scale tool. Specifically, do I need to complete scale factors for all bodies prior to running the scaling tool? I would...

Thanks for reply, but both disply_prefs elements were set to zero. In general it seems there is some issue displaying the model correctly and consistently. For example, when I close and reopen the model different wrap objects are displayed than where displayed the previous time the file was opened. ...

Simao,

Same issue w/ me as well. Also using OpenSim 3.3 (v64) w/ Win10 PC. I really hope this gets sorted out in OpenSim 4.0. I may try Beta version of OpenSim 4.0 in mean time.

I just navigated this very same path :-).Depending on the source of your experimental marker data, there are several tools that can reorient your experimental marker data to match the OpenSim model coordinate system orientation. See here: https://simtk-confluence.stanford.edu/display/OpenSim/Tools+f...

I have somehow triggered the display of wrapped objects in my model. I am sometimes able to (re)hide them by resetting the display_preferences back to 0 (from 4) but other times this does not seem to work. I also get a java related exception error. The text of the error is below. I have also attache...

Was the "phantom" mystery ever resolved? I am now trying to use the MoBL-ARMs UE (https://simtk.org/projects/upexdyn) but do not understand what the scapphant, clavphant and humphant bodies are for especially since they all have zero inertial properties.
