Hi,
I am getting the following error when I am trying to convert my c3d files to opensim compatible files. But the example works good. Can you help me on this.

Error:
Reference to non-existent field 'MARKER_SETS'.

Error in btk_loadc3d (line 161)
sub_info.MarkerSet = md.children.SUBJECTS.children.MARKER_SETS.info.values{1};

Error in opensim_walking_pipeline (line 29)
data = btk_loadc3d([pname, fname], 10);

Specs:
Opensim 4.0
Windows 10.
Opensim bin folder in Environmental Variables-> Path

Thanks,
Mritula
