Hi,

Just try to change the initial position of human model in ‘TrialSpecificData’ folder.

AnyFolder InitialPositionOfBody =
  {  
    AnyVar PelvisRotZ = -90;
    AnyVar PelvisRotY = 0;
    AnyVar PelvisRotX = 90;
....

Then you can ‘run’ this model. There will be always a way to run the models.

Best regards,
Moonki

Hi,

I would suggest you to follow ‘Making things move’ chapter in the AnyBody tutorial.
It will be very important for you to understand this chapter 100% if you want to be familiar with GaitFullBody example using C3D files.

Also you can see the following wiki page which will be helpful for you.

Hi sambom,

This error occurs if you try to use the CreateMarkerClassTD on a bone which is not originating from the TDleg model.

So if you try to use this class for creating a marker on the trunk for example. For other bodyparts than the TDleg model you need to use CreateMarkerClass instead.

Thank you, message.
I use CreateMarkerClass without TDleg.
Sorry, is it correct?
But I can’t run.
What is wrong?

Hi Sambom,

I have looked at the model
You are using the Leg model not LegTD this i can see this in the bodypartssetup.any file

In the Modelsetup1001??.any i can see you are using the CreateMarkerClassTD and this combination will not work together and it will give you this error.

Why are you suing the Leg model and not the LegTD? i think you would have less problems if you swapped back to the other leg model as it is originally defined in the GaitLowerectremity model.

Thank you message.

I don’t understand to change ClassMarker to ClassMarkerTD.

I try to change it .
Sorry, is it correct?

Should I use GaitLowerExtremityModel?

Hi Sambom,

I have checked the ModelSetup100…any file and it seems to look ok in principle, it looks like you have changed all instances of CreateMarkerTD to CreateMarker… Please note that when you do this the sRelOpt values may not be the same anymore and need to be changed.

This is why i asked about why you are not using the GaitLowerExtremity model but are trying to use an older leg model instead on the more recent LegTd model?

If you used the gaitlower extremeity model or the fullbodygait model model this would already be using this model, but i do not know if there is a specific reason for shifting to the other leg model?

Best regards

Thank you message, toerholm.

Sorry,I don’t know characteristic of GaitLowerExtremity and GaitFullBody.

I tend to use AMMRV1.5’s GaitFullBody.
But I can’t run it .

Hi Sambom,

Please explain what you would like to obtain with the model and which data you have available, this will aloow us to help you more efficiently.

What type of motion?
Which markers do you have: lower extremities, trunk, arms?

When you say you can not run the GaitFullBodyModel i do not understand why?

My advice without knowing more of your problem: Start using the GaitLowerExtremityModel (if you do not have upper body markers) as it is from the repository, alternative the fullbodygaitmodel if you also have arms markers.

Best regards

Thank you message, toerholm.
I want to run inversedynamics by using this model and text data of force plate.
The c3d data is entering and exiting motions of automobile.
Because this data is whole body movement ,
I think use GaitFullBody.

15

Hi Sambom,

In this case please try to use the GaitFullBody model and do not make changes in the BodyPartSetup.any files to other leg models, since this will cause you more work, and i do not see any gains by doing it.

Best regards
Søren

Thank you message, toerholm.

I can run inversedynamics .
But , this c3d file don’t have external force.
So, I want to use text file of external force.

But, I can’t run it.
Please check this file.
