[Genome] Converting Genome Coordinates

[Katie F Wlaschin]

Hello - I want to convert the coordinates from the human/mouse/rat 
alignment from the NCBI human 34 build / mouse 30 and rat 3  to the most 
updated coordinates from the most recent mouse assembly.  I've tried 
your lift-over tool and most of the start-stop coordinates are "split" 
so its a little difficult.  Is there a similar table that defines the 
start-stop coordinates for the most updated assemblies

Thank you - Katie
