[Genome] how scaffold-->chrUn?

[Ann Zweig]

Hello Xianjun,

	I'm not sure I understand exactly what you are asking.  Are you saying 
that you would like to know how to convert from scaffolds to chrUn?

	In our browser, ChrUn contains clone contigs that can't be confidently 
placed on a specific chromosome. For the chrN_random and chrUn_random 
files, we essentially just concatenate together all the contigs into 
short pseudo-chromosomes. The coordinates of these are fairly arbitrary, 
although the relative positions of the coordinates are good within a contig.

	If this does not answer your question, please don't hesitate to write 
back to the list with more detailed information.

Regards,
