Hello everyone
Rencently, I started to using Opensim, I using my mocap data, normal walking of older adults. I can running IK and ID analysis successfull, but when i running the RRA, model will disappear. I notice that if iam not setting external force, namely grf data, the model will not disappear, but will fallingin sky untill analysis end. I suppects the reason of this sitituion mayble because my mot file. However, i using the matlab code, calling exportC3D, i think many people to using this code to perprocessing the trc and mot file, but ther don't have this problems. So if anyone can help, thanks to much.
Your Sincerely.
