[Genome] Relationship between 'phastCons17way' and 'phastConsElements17way'?

[Ann Zweig]

Hello Gordon,

	The phastCons17way table underlies the wiggle part of the Conservation track 
while the phastConsElements17way underlies the Most Conserved track.  The Most 
Conserved track shows predictions of conserved elements produced by the 
phastCons program.  You can read details about the methods used to produce each 
of the tables by clicking on the track name hyper link in the track controls 
below the Genome Browser track image.

	I think that you will want to use the phastConsElements17way for your queries.

	Please let us know if you need more details or if this doesn't quite answer 
your question.


Regards,
