[Genome] BAC track

[Brooke Rhead]

Hello Shlomit,

Each BAC end pair consists of a + strand read from one end of the BAC 
and a - strand read from the other end of the BAC.  You should see one + 
and one - alignment if you click on the details page for any BAC end pair.

Each BAC pair can be oriented in either direction when compared to the 
genomic sequence, indicated in the "strand" field.  See an explanation 
in this previously-answered question:

I hope this answers your question.
