Hi Umut,

I'm not quite sure I understand your question. The third tag tells how 
many partitions an element belongs to; the next tags give these 
partitions' ids. If a partition id is negative, it denotes a partition 
in which the element is a ghost cell.

Is the confusion linked to the negative ids? (At the moment there is no 
option to disable ghost cells--you need to recompile from the sources.)
