This directory contains conservation scoring by phyloP (phylogenetic p-values)
from the PHAST package (http://compgen.bscb.cornell.edu/phast/).
for multiple alignments of 43 vertebrate genomes to the human genome,
plus alternate sets of scores for the primate species and the placental mammal 
species in the alignments.

Files in this directory are:
    vertebrate/*.wigFix.gz phyloP scores for all 44 species
    primates/*.wigFix.gz  phyloP scores for primate subset
    placentalMammals/*.wigFix.gz  phyloP scores for placental mammal subset

The multiple alignments and methods description are at:

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 rsync or ftp rather than downloading the files via our website:

   rsync -avz --progress \
        rsync://hgdownload.cse.ucsc.edu/goldenPath/hg18/phyloP44way/ ./

      OR

    ftp hgdownload.cse.ucsc.edu 
    user name: anonymous
    password: <your email address>
    go to the directory goldenPath/hg18/phyloP44way

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.
