Force Plate error

Main Forum

Hi,

I wanted to run shoulder model from Vicon Mocap data for future EMG validation. We registered a lifting box trial with the force sensor in the right hand, then the data form the sensor was convert to ForcePlateType2 and resave into c3d file.

At the beginning I followed the wiki Mocap instruction and I was trying to adapt MoCap Full Body model to my data.

When I tried to include the force plate I got an error:

ERROR(SCR.EXP0) : E:/A…3/AMMR/A…n/E…s/M…N/I…t/ForcePlates.any(12) : Defined at : E:/A…3/AMMR/Body/A…n/T…x/M…p/ForcePlateType2.any(12) : ‘sRel’ : Error in expression. Please refer to the following error messages for details …
ERROR(SCR.EXP3) : E:/A…3/AMMR/A…n/E…s/M…N/I…t/ForcePlates.any(12) : Defined at : E:/A…3/AMMR/Body/A…n/T…x/M…p/ForcePlateType2.any(12) : ‘sRel’ : Index [0] out of range for ‘AnyFloat’

I guess this is the problem of the structure of my c3d file. It also includes the the EMG data that are saved under analog channel and data from force platform starts from index 19.

I attached my c3d file.

Thank you for your help in advance.

Dear Marta,

When I looked at your C3D file, this C3D does not seem to include the correct information of a force plate.

Usually there should be corners and origin locations of force plates, the in your C3D file there is no such information.

So you should prepare a correct C3D file which include all necessary information of a force plate.
