Human/hg19/GRCh37 46-way multiple alignment

The 46 species multiple alignment on human/hg19/GRCh37 is an extra large bit of work. A discussion of the phylogenetic trees used in the alignment is included here.

Errata

The initial release of this track include a phylogenetic tree that had two small errors in it. 46way.nh
Namely: Baboon (papHam1) and Rhesus (rheMac2) were specified as separate nodes instead of correctly sister species. The same problem is present for Wallaby (macEug1) and Opossum (monDom5). The discussion below includes a corrected phylogenetic tree.

Corrected Tree

I'm currently rerunning a test with the multiple alignment and phastCons/phyloP annotations to see if the corrected tree makes any significant difference in the result. I'm expecting the difference to be minor. In the meantime, included here is a corrected tree:
