This directory contains compressed multiple alignments of the
following assemblies to the human genome (hg38, Dec. 2013):
Assemblies used in these alignments:
Human Homo sapiens Dec. 2013 (GRCh38/hg38) reference
Mouse Mus musculus Dec. 2011 (GRCm38/mm10)
Chinese tree shrew Tupaia chinensis Jan. 2013 (BGI TupChi_1.0/tupChi1)
Malayan flying lemur Galeopterus variegatus Jun. 2014 (WashU G_variegatus-3.0.2/galVar1)
These alignments were prepared using the methods described in the
track description file:
http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=hg38&g=cons4way
based on the phylogenetic tree: hg38.4way.nh.
Files in this directory:
- hg38.4way.nh - phylogenetic tree used during the multiz multiple alignment
- hg38.4way.commonNames.nh - same as hg38.4way.nh with the UCSC database
names replaced by the common name for the species
- hg38.4way.scientificName.nh - same as hg38.4way.nh with the UCSC database
names replaced by the scientific name for the species
- upstream*.knownGene.maf.gz - alignments of regions upstream of UCSC genes
- hg38.4way.maf.gz - the multiple alignments on the human genome
- md5sum.txt - md5 check sums of these files to verify correct download files
The "alignments" directory contains compressed FASTA alignments
for the CDS regions for the gene track knownGene (March 2016 version)
of the human genome (hg38, Dec. 2013) aligned to the assemblies.
The hg38.4way.maf.gz file contain all the alignments for the chromosomes
in the human genome, including additional annotations to indicate gap
context and genomic breaks for the sequence in the underlying
genome assemblies. Note, the compressed data size of the
maf file is 3.0 Gb, uncompressed is more than 13 Gb.
The .upstream*.*.maf.gz files contain alignments in regions upstream of
annotated transcription starts for version 81/July 2015 Ensembl 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.

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 240 Mb of compressed data in this directory.
Via rsync:
rsync -av --progress \
rsync://hgdownload.cse.ucsc.edu/goldenPath/hg38/multiz4way/ ./
Via FTP:
ftp hgdownload.cse.ucsc.edu

go to the directory goldenPath/hg38/multiz4way
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.
