MoCap Model-Neck posture

Hi AnyBody Team

I am uploading my AnyBody Model here. Both head and neck are less forward in the model compared to Vicon. Is it possible to simulate neck protraction with MoCap Model?

There are six C3D files in the Input folder. I encountered the problem in two files namely “Upright-protraction” and “slump-protraction”.

It would be great if you can tell me whether AnyBody can simulate this extreme head-neck posture.

Did you edit the marker positions? Did you record yourself and do you know where the markers have been placed on the body?
If you edit the markers, in particular on sternum and clavicula you will get a better match on the head.

Yes I did. Other movements seem to be good, but only protraction does not work well as you can see in the model I just uploaded.

I made some changes, excluded the arms for now and thought it looked better.

Hi Amir

But there still exists problem. Since arms were excluded, I can not perform inverse dynamic operation.

Error(OBJ1): BodyModel.UnhallowedCombination : Combination is not allowed: As some neck muscles are in the shoulder model, the neck model with muscles must be used with the neck part of the shoulder muscles to be complete.
