c3d file problems

Hi again,

as I already wrote I have some problems with C3D file. I use the AMS version 5.3.1 and AMMR.v.1.5.1. I use the C3D file in GaitFullBody model, both enclosed in zip file. When I load it I get this error message:

ERROR(SCR.PRS9) : D:/U…s/L…a/r…y/A…x/A…o/A…n/E…s/G…y/ModelSetup.any : Defined At : D:/U…s/L…a/r…y/A…x/A…o/Body/A…n/T…x/M…p/CreateMarkerClassTD.any : ‘PosInterpol’ : Unresolved object

The only one thing I changed are names of two markers in ModelSetup.any (RFRA, LFRA to RFRM, LFRM). These names weren’t the same in model and in the c3d file.

Thank you very much,
Linda

Hi Linda,

Attached please find the modified version of your model.

  1. There are two markers which you might miss the name change: L5MT, R5MT.

So I modified the names of those markers in the C3D file so now their names are LMT5 and RMT5.

  1. In your C3D the type of force plate is 2.
    So you should use the class template of the force plate type 2.

I would suggest you to read the following tips:

Hi,
I have some problems with C3D file again, so I ask you for advice. I’m still using the AMS version 5.3.1 and AMMR version 1.5.1. Now I use the model GaitLowerExtremity – only the lower body part, enclosed in zip file. I have 16 markers in my C3D file (called “Chuze3.c3d”). The marker names are “Bacevsky:RASI”, “Bacevsky:LTOE”, etc. When I change the marker names according the file I get the following error:

ERROR(SCR.SCN6) : D:/U…s/L…a/TACR/AMMR/A…n/E…s/G…s/ModelSetup.any : ‘:RTHI’ : Unexpected character.

Is it possible to use the colon in the name?

Moreover when I want to set the prefix name which goes in front of all markers, nothing will change. I get the same error as I would not change anything:

ERROR(SCR.PRS9) : D:/U…s/L…a/TACR/AMMR/A…n/E…s/G…s/ModelSetup.any : Defined At : D:/U…s/L…a/TACR/AMMR/Body/A…n/T…x/M…p/CreateMarkerClassTD.any : ‘PosInterpol’ : Unresolved object

So please, could you help me how can I implement my C3D file?
Thank you very much,
Linda

Dear LInda,

Can you please update to a more recent model? With a newer model it would be a lot easier for us to help.

A colon is replaced by a 58 , so I would suggest for your model , in the ModelSetup file to not use the prefix, but just edit the Marker names

from
MarkerName=PrefixDef(RTHI),
to
MarkerName=Bacevsky_58_RTHI,

and in the Mannequinnfile:

AnyParamFun &RASI = Main.ModelSetup.C3DFileData.Points.Markers.Bacevsky_58_RASI.PosInterpol;
AnyParamFun &LASI = Main.ModelSetup.C3DFileData.Points.Markers.Bacevsky_58_LASI.PosInterpol;

AnyParamFun &RPSI = Main.ModelSetup.C3DFileData.Points.Markers.Bacevsky_58_RPSI.PosInterpol;
AnyParamFun &LPSI = Main.ModelSetup.C3DFileData.Points.Markers.Bacevsky_58_LPSI.PosInterpol;

that should hopefully do the trick.
