Hi, I was trying to put some data I get from my lab in the model with only legs, I used the same data before for a complete model (just without arms) and the scaling process succeeded, now I was trying to do the same with just both legs, I cut off from files the marker I didn’t add to the model, but...

Hi, I was interested in running Static Optimization, but from the beginning I noticed that it takes too long time , so I understand that the muscles of my model are weak(the message show me that "The model appears too weak for static optimization") so, I was wandering, what I have to do now, I have ...

Hi, using the tool scale, I was wondering why even if my static.trc file has not exactly all the same marker name that are in the model, if I used it in Marker data for measurements, the program is able to run and to scale the model (the same thing is not possible with the adjust model markers where...

Hi Ayman, thank you very much, I succeeded in synchronizes movement and it was very useful to check everything before plotting! Yes, effectively I didn’t use the Kinematic for external load and it seems to work

Thanks again!

Hi Ayman, Thank you very much, before I read this post I decided to re-install the program, I didn’t change anything else, and then everything was ok. I’m sorry but I didn’t found other way to get out of it in that moment! But If the problem will occur one more time I’ll try your suggestion. Thank y...

Hi, Today I have a problem with the Inverse Kinematics tools, I used it several time in my 3 models and it has always worked fine! Yesterday I was working with the Inverse Dynamic tool and I tried to use the preview Motion to see the forces and motion synchronized but they didn’t were ok, anyway I t...

Hi, I read something about that also here in the forum, but I’m sorry I’m still a little bit confused… I noticed that to create my own External Force file.xml I need a Force data file (ok, I get it with external loads,Cop, and Torque in every frame) and a kinematics for external loads file, now, I h...

Hi, thanks to your help I found out the problem! The indicted marker were placed in the ground instead of in pelvis etc... Thank you very much, I'm sorry I didn't think about it at all!

Best wishes

Hi Ayman, thank you for your help :) To scale my model I used a OpenSim model without marker and I added marker myself, then by using the GUI I checked “Preserve mass distribution during scale” and “Marker data for measurement” where I browsed a Static file .trc, I checked also “marker data for stat...

Hi, I have a little problem with my model when I tri to scale it by using GUI: I used a Opensim model, I added marker, and used a .trc file to scale it, at first it appears correct with blue marker in almost the right position, but then, when I save this scaled-model, I close it and I re-open it, it...
