Genetic maps (gifs) in _C. elegans_ acedb

[Chris B.]

	Could someone tell me how to interpret the genetic map
gifs found in the _C. elegans_ acedb?  In particular, I'd like to
know what the vertical line in the center of the gif with loci 
next to it covers.  Does it signify the high-lighted deletion
range to the left or some other range?
	A place to look for this information would also do fine.

Thanks all,

Chris Bauer
