LiftOver of tracks from hg18 to hg19

The tracks indicated by the logo hg18 LiftOver logo or hg19 LiftOver logo have been lifted from hg18 or hg17, respectively, with a minimum of quality control scrutiny. They are provided to our users with the intent that they assist in interpretation of other data, but must be used with caution. Not all annotations remain intact when lifted in this manner and in any case, cannot by definition contain any sequence that is new to hg19.

It should also be noted that tracks containing large regions will lift less well because of the increased chance of spanning a region that changed between the two assemblies.
