RE: FAQ Marker Set and Force Platform Data


On the weights tab of the IK tool you can disable whatever markers that you do not want to track.

Force data is imported through the motion file input for IK and is carried over to IK output motion for later usage.

Hope that helps,

RE: FAQ question: C3D Files

As of version 1.0, OpenSim does not read C3D files directly. Users need to preprocess these files to put their data in the file formats that OpenSim supports:

.mot SIMM motion files
.trc Motion capture files
