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.

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.
