How to straighten the vertebrae of a spine

[Martina Pedroli]

Hi everybody, I am developing a musculoskeletal model of a dog on opensim and I have some doubts. The spine that I obtained from scans and on which I will create my model is distorted and I would need to straighten it. The cadaver I used was badly positioned and at the moment I can't do any more scans so I have to fix what I have. Would it be straightening the vertebrae using Opensim?
I hope someone can help me or give me some advice.
Thanks, Martina
