This directory contains compressed multiple alignments of the
following assemblies to the human genome (hg38/GRCh38, Dec. 2013):
Assemblies used in these alignments: (alignment
type)
Human - Homo sapiens Dec. 2013 (GRCh38/hg38) reference
Chimp - Pan troglodytes Feb. 2011 (GSAC 2.1.4/panTro4) syntenic
Rhesus - Macaca mulatta Oct. 2010 (BGI CR_1.0/rheMac3) syntenic
Dog - Canis lupus familiaris Sep. 2011 (Broad/canFam3) syntenic
Mouse - Mus musculus Dec. 2011 (GRCm38/mm10) syntenic
Rat - Rattus norvegicus Mar. 2012 (RGSC Rnor 5.0/rn5) syntenic
Opossum - Monodelphis domestica Oct. 2006 (Broad/monDom5) net
---------------------------------------------------------------
These alignments were prepared using the methods described in the
track description file:
http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg38&g=cons7way
based on the phylogenetic tree: hg38.7way.nh
Files in this directory:
- hg38.7way.nh - phylogenetic tree used during the multiz multiple alignment
- hg38.7way.commonNames.nh - same as hg38.7way.nh with the UCSC database
name replaced by the common name for the species
- upstream1000.knownGene.maf.gz - alignments in regions upstream, see below
- upstream2000.knownGene.maf.gz - alignments in regions upstream, see below
- upstream5000.knownGene.maf.gz - alignments in regions upstream, see below
- hg38.7way.maf.gz - alignmens with gap annotation

The "alignments" directory contains compressed FASTA alignments
for the UCSC Known Gene CDS regions of the human genome
(hg38, Dec. 2013) aligned to the assemblies. Additional
alignment files are provided for RefSeq genes, and the
UCSC Known Gene canonical genes.
The hg38.7way.maf.gz file contains the alignments to
the human assembly, with additional annotations to
indicate gap context, and genomic breaks for the
sequence in the underlying genome assemblies. Beware, the compressed
data size of this file is 3.5 Gb, uncompressed is approximately 17 Gb.
The upstream*.maf.gz files contain alignments in regions upstream of
annotated transcription starts for UCSC Known 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
mouse, 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 the human sequence; 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.
For a description of multiple alignment format (MAF), see
http://genome.ucsc.edu/goldenPath/help/maf.html.

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 31 Gb of compressed data in this directory.
Via rsync:
rsync -avz --progress \
rsync://hgdownload.cse.ucsc.edu/goldenPath/hg38/multiz7way/ ./
Via FTP:
ftp hgdownload.cse.ucsc.edu
user name: anonymous
password: <your email address>
go to the directory goldenPath/hg38/multiz7way
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.
