This directory contains compressed multiple alignments of the 
following assemblies to the opossum genome (monDom4, Jan. 2006):

  - opossum (Jan 2006, monDom4)
  - human (Mar 2006, hg18)
  - mouse (Feb 2006, mm8)
  - rat (Nov 2004, rn4)
  - chicken (Feb 2004, galGal2)
  - frog (Aug 2005, xenTro2)
  - zebrafish (Mar 2006, danRer4)

The chr*.maf.gz files each contain all the alignments to that 
particular opossum chromosome.

If you plan 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 to hgdownload.cse.ucsc.edu, 
then go to the directory goldenPath/monDom4/multiz17way. To download 
multiple files, use the "mget" command:

    mget <filename1> <filename2> ...
   - or -
    mget -a (to download all the files in the directory) 

All the files in this directory are freely usable for any 
purpose. For data use restrictions regarding the individual 
genome assemblies, see http://genome.ucsc.edu/goldenPath/credits.html.
