These alignments were prepared using the methods described in the
track description file, multiz28way.html, based on the 
phylogenetic tree, 28way.nh.

The maf/chr*.maf.gz files each contain all the alignments to that 
particular human chromosome.  The multiz28wayAnno.tar.gz file
contains the same alignments for all chromsomes, 
with additional annotations to indicate gap context, genomic breaks, 
and quality scores for the sequence in the underlying genome assemblies.

The maf/upstream*.maf.gz files contain alignments in regions upstream of
annotated transcription starts for RefSeq genes with annotated 5' UTRs.
These files differ from the standard MAF format: they display
alignments that extend from start to end of the upstream region in 
human, whether or not alignments actually exist. In situations where no  
alignments exist or the alignments of one or more species are missing, 
dot (".") is used as a placeholder. Multiple regions of an assembly's
sequence may align to a single region in human; therefore, only the 
species name is displayed in the alignment data and no position information 
is recorded. The alignment score is always zero in these files. These files
are updated weekly.

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 hgdownload.cse.ucsc.edu 
    user name: anonymous
    password: <your email address>
    go to the directory goldenPath/hg18/multiz28way

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.
