This directory contains conservation soring by phyloP (phylogenetic p-values)
for multiple alignments of 28 vertebrate genomes to the human genome,
plus an alternate set of scores for the placental mammal
subset of species in the alignments.  

Files in this directory are:
    vertebrate/*.wigFix.gz  scores for all 28 species
    placental/*.wigFix.gz   scores for placental subset (18 species)

The multiple alignments and methods description are at:

For more information about this data, see the track
description for the Basewise Conserv track.

The tree models used to generate this track are available at:

To download a large file or multiple files from this directory, we recommend 
that you use ftp rather than downloading the files via our website. To do so: 
    ftp hgdownload.cse.ucsc.edu 
    user name: anonymous
    password: <your email address>
    go to the directory goldenPath/hg18/phastCons28way

To download multiple files from the UNIX command line, use the "mget" command. 
    mget <filename1> <filename2> ...
    - or -
    mget -a (to download all the files in the directory) 
Use the "prompt" command to toggle the interactive mode if you do not want 
to be prompted for each file that you download.
