Is there any way to find vertix belonging More then 1 Group.

I am trying to rig one character from MakeHuman and finding some problem that there is some vertix belongs to NO Group and some belongs to more then one group.
Is any way in the Python to find out?
Please help…

I think you can get pretty far by just using http://www.blender.org/documentation/244PythonDoc/Mesh.Mesh-class.html#getVertGroupNames and http://www.blender.org/documentation/244PythonDoc/Mesh.Mesh-class.html#getVertsFromGroup . After you have the vertex groups, iterate through them and store found verts. If already found vert is found again, it belongs to more than one group.

To figure out if a vertex doesn’t belong to any group, you could first check if this is possible (does amount of non-duplicate vertices match amount of all vertices). If it is, get all verts and “subtract” ones in vertex groups from it. That should give vertices without a group.
