[Genome] Difference between Genome Browser and Table Browser output

[Pang Ko]

Hi,

  I am interested in the location chr12:64912201-64912645 in human genome (hg17)

  I am using the Genome Browser with
Genome: Human
Assembly: May 2004
  and choose Track Conservation to be full. Then I click on the
conservation track and then choose rat in the multiple alignment, it
will bring me to rat genome location chr7:59446696-59,444,569 (rn3).

  When I use Table Browser and choose
Genome: Human
Assembly: May 2004
Group: Comparative Genomics
Track: Conservation
table: multiz17way
Position: chr12:64912201-64912645

  The output of table browser shows an alignment with rn3 location
chr7:83636219-83638448

  My question is why are the two output different? (one shows
alignment with chr7:59446696-59444569 and the other shows
chr7:83636219-83638448 in the same assembly) Did I do something wrong?

Thank you,
Ko.
