Cannot Get Data Into OpenSim

[Patrick Rider]

We are using a Qualisys Motion Capture system and an AMTI forceplate and cannot seem to get everything set up correctly to easily get data into OpenSim. Are any of you currently using similar equipment and if so, what are your setup parameters you are utilizing? thanks in advance for any help you can provide.

Patrick:
It´s a format problem you need to put the cinematic data in a .trc file you can look the examples file included in the installation, same for the forceplates in a .mot file.

hope it helps.

Yeah i've gotten the some matlab scripts from the developers workshop, however i'm having trouble setting up our lab coordinate system to collect with OpenSim conventions (Fy as vertical coordinate/Fz as medial lateral coordinate). Thanks for the post though!

You do not have to set up your lab for opensim convention, if this is what is causing the problem. You can collect the data and apply rotational transformation to convert in its convention.

I hope I am understanding the question right.

Hi, may I get the MATLAB script from you as I cannot convert the file obtained in Qualisys to .trc format which is required in OpenSim.
