Hi Thomas,

In order to further assist you, we will need to see the original data 
and bigBed you created. In addition, where did you obtain the program, 
from our hgdownload binaries or built locally in the source tree? What 
is your environment (from the 'uname -a' command output)? Please reply 
to [email protected].

Regards,
