Arena Skeleton and tracking Errors. Can they be fixed?

Hello,

I have a couple different problems and I would greatly appreciate any help you can offer.

I have collected motion data using an 11 camera setup on martial artists collecting at 100 fps. The speed of these Sifu creates tracking problems and it was not uncommon for a particular anatomic segment (such as the right arm)to turn red. The tracking system was unable to identify where that particular segment was despite the markers being visible on the screen. I tried to figure out a way to manually assign these marker locations. I selected the Assign Object button and instead of manually assigning the marker locations it added more markers to the skeleton. I left arena without saving, however, the skeleton was automatically saved. Thus every time I load the project file there are more markers assigned to this segment. (in my case... The head should have 3 markers I apparently added 5 markers to the head segment and it now shows a total of 8 markers when I select the assign object button)

Is there a way to fix my screw up and remove the additional markers I accidently assigned to the segment? (I originally used the 38 marker skeleton wizard)Also is there a way to manually select and assign a particular marker as one of the markers used in the skeleton?

Any information on removing the markers I obliviously added to the skeleton would be greatly appreciated!

I just restored the skeleton to a previous version and fixed my mistakes... so luckily I didn't ruin the data I collected on this talented martial artist.

I am still however curious if I can manually locate and assign markers visible in the capture area as being part of a particular segment.

For example...

If the tracking cant find the right hand, but the markers are visible. Can I manually assign the visible markers as right hand1, hand2, and hand3?
