This directory contains conservation scoring by phyloP (phylogenetic p-values)
from the PHAST package (http://compgen.bscb.cornell.edu/phast/) for multiple
alignments of 6 vertebrate genomes to the human genome.

Files in this directory:

    hg38.phyloP7way.mod - phyloP tree model with branch lengths for
                            all 7 species
    hg38.phyloP7way.bw - scores in bigWig format
    hg38.phyloP7way.wigFix.gz - scores in fixed step wiggle format

For a description of the fixed step wiggle data file format, see:

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/hg38/phyloP7way/ ./

      OR

    ftp hgdownload.cse.ucsc.edu 
    user name: anonymous
    password: <your email address>
    go to the directory goldenPath/hg38/phyloP7way

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.
