This directory contains conversation scoring by phyloP (phylogenetic p-values)
from the PHAST package (http://compgen.bscb.cornell.edu/phast/) for multiple
alignments of 4 genomes to the human genome.

Files in this directory are:

    hg38.phyloP4way.mod  phyloP tree model with branch lengths
                        for the 5 genomes
    hg38.phyloP4way.wigFix.gz - phyloP scores for the 5 genomes
                                 in fixed step wiggle format
    hg38.phyloP4way.bw - phyloP scores for the 5 species
                          in bigWig format
    md5sum.txt - md5 sums of the files here to verify accurate download

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 5.6 Gb of compressed data in this directory.

Via rsync:
rsync -avz --progress \
	rsync://hgdownload.cse.ucsc.edu/goldenPath/hg38/phyloP4way/ ./

Via FTP:
    ftp hgdownload.cse.ucsc.edu 
    user name: anonymous
    password: <your email address>
    go to the directory goldenPath/hg38/phyloP4way

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.
