Hello all
Please can you advise me what sequences the ChrUn numbers returned by
liftover refer to. For example a liftover performed on bos taurus from
MD3 to Btau4 returned mappings such as
chrUn.004.1000 244 245
A search in entrez for a sequence 'chrUn.004.1000' or '004.1000'
returns nothing.
I do not know whether these sequences refer to unlocalized sequences or
unplaced sequences (see definitions below)
thanks
Unlocalized sequence:
A sequence found in an assembly that is associated with a specific
chromosome but cannot be ordered or oriented on that chromosome.
Unplaced sequence:
A sequence found in an assembly that is not associated with any
chromosome.
