2BIT format?

[Olivier Friard]

Hi,
I found on the new release of EMBL (53) at EBI a directory named GCG that 
contains 2 types of files (.SEQ and .REF). In the .SEQ file, they are 2 
types of sequences: the first one type is classic readable ASCII but 
the second one is 2BIT unreadable format. Does someone know how read this 
2BIT format?

Thanks

Olivier
