This directory contains compressed multiple alignments of the 
following assemblies to the lamprey genome (petMar2/WUGSC 7.0, Sep. 2012)

                                                                     (alignment

These alignments were prepared using the methods described in the
track description file:
http://genome.ucsc.edu/cgi-bin/hgTrackUi?db=petMar2&g=cons7way
based on the phylogenetic tree: petMar2.7way.nh.

Files in this directory:
 - petMar2.7way.nh - phylogenetic tree used during the multiz multiple alignment
 - petMar2.7way.commonNames.nh - same as petMar2.7way.nh with the UCSC database
       name replaced by the common name for the species
 - upstream1000.xenoRefGene.maf.gz - alignments in regions upstream, see below
 - upstream2000.xenoRefGene.maf.gz - alignments in regions upstream, see below
 - upstream5000.xenoRefGene.maf.gz - alignments in regions upstream, see below

The two files: xenoRefGene.exonAA.fa.gz xenoRefGene.exonNuc.fa.gz
contain compressed FASTA alignments for the Xeno RefSeq CDS regions
of the lamprey genome (petMar2, Apr. 2012) aligned to the assemblies.

The petMar2.7way.maf.gz file contains the alignments to
the lamprey 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 these this is 140 Mb, uncompressed is approximately 574 Mb.

The upstream*.maf.gz files contain alignments in regions upstream of
annotated transcription starts for Xeno 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 
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 lamprey; 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 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/petMar2/multiz7way/ ./

Via FTP:
    ftp hgdownload.cse.ucsc.edu 
    user name: anonymous
    password: <your email address>
    go to the directory goldenPath/petMar2/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.
