Hi all,

I am developing lower extremity models from MRIs and I need to account for the fact that the joints were not scanned at exactly 0* according to the definitions I would like to use. Is there a simple way using OpenSim to adjust the 0* position of the joint? I have my joint reference systems defined properly so for example I would like to remove 5* of hip flexion, so that what is currently defined as -5* hip flexion in my model becomes 0*.

Thanks,
Colin

Hi Colin-
You can adjust the bodies orientation (in its parent) using the 'orientation tag in the osim file:
<orientation> 0 0 0</orientation>
Note, it is in radians.
