This directory contains conservation scoring by phyloP (phylogenetic p-values)
from the PHAST package (http://compgen.bscb.cornell.edu/phast/) for multiple
alignments of 7 fish genomes to the Fugu genome.

Files in this directory are:
    fish.mod - phyloP tree model with branch lengths for all 8 species:
                        fugu, tetraodon, nile tilapia, stickleback, medaka,
                        atlantic cod, zebrafish, coelacanth)

    phyloP8way.wigFix.gz phyloP scores for all 8 species, wiggle fixed step
    phyloP8way.bw phyloP scores for all 8 species in bigWig format

The multiple alignments and methods description are 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.
There is approximately 1.8 Gb of compressed data in this directory.

   rsync -av --progress \
        rsync://hgdownload.cse.ucsc.edu/goldenPath/fr3/phyloP8way/ ./

      OR

    ftp hgdownload.cse.ucsc.edu 
    user name: anonymous
    password: <your email address>
    go to the directory goldenPath/fr3/phyloP8way

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.
