This directory contains the Sep. 2007 assembly of the horse genome
(equCab2, Broad Institute EquCab2), as well as repeat annotations and GenBank
sequences.
This assembly was produced by the Broad Institute at MIT and Harvard.
For more information on the horse genome, see the project website:
http://www.broad.mit.edu/mammals/horse/
Files included in this directory:
equCab2.2bit - contains the complete horse/equCab2 genome sequence
in the 2bit file format. Repeats from RepeatMasker and Tandem Repeats
Finder (with period of 12 or less) are shown in lower case; non-repeating
sequence is shown in upper case. The utility program, twoBitToFa (available
from the kent src tree), can be used to extract .fa file(s) from
this file. A pre-compiled version of the command line tool can be
found at:
http://hgdownload.cse.ucsc.edu/admin/exe/linux.x86_64/

chromAgp.tar.gz - Description of how the assembly was generated from
fragments, unpacking to one file per chromosome.
chromFa.tar.gz - The assembly sequence in one file per chromosome.
Repeats from RepeatMasker and Tandem Repeats Finder (with period
of 12 or less) are shown in lower case; non-repeating sequence is
shown in upper case.
chromFaMasked.tar.gz - The assembly sequence in one file per chromosome.
Repeats are masked by capital Ns; non-repeating sequence is shown in
upper case.
chromOut.tar.gz - RepeatMasker .out files (one file per chromosome).
RepeatMasker was run with the -s (sensitive) setting.
Jan 11 2008 (open-3-1-9) version of RepeatMasker, RELEASE 20071204.
chromTrf.tar.gz - Tandem Repeats Finder locations, filtered to keep repeats
with period less than or equal to 12, and translated into UCSC's BED
format (one file per chromosome).
est.fa.gz - Horse ESTs in GenBank. This sequence data is updated once a
week via automatic GenBank updates.
equCab2.quals.fa.gz - quality scores in fasta file format
md5sum.txt - checksums of files in this directory
mrna.fa.gz - Horse mRNA from GenBank. This sequence data is updated
once a week via automatic GenBank updates.
refMrna.fa.gz - RefSeq mRNA from the same species as the genome.
This sequence data is updated once a week via automatic GenBank
updates.
upstream1000.fa.gz - Sequences 1000 bases upstream of annotated
transcription starts for RefSeq genes with annotated 5' UTRs.
This file is updated weekly so it could be slightly out
of sync with the RefSeq data which is updated daily for most
assemblies.
upstream2000.fa.gz - Same as upstream1000, but 2000 bases.
upstream5000.fa.gz - Same as upstream1000, but 5000 bases.
xenoMrna.fa.gz - GenBank mRNAs from species other than that of
the genome. This sequence data is updated once a week via automatic
GenBank updates.
equCab2.chrom.sizes - Two-column tab-separated text file containing assembly
sequence names and sizes.
equCab2.chromAlias.txt - sequence name alias file, one line
for each sequence name. First column is sequence name followed by
tab separated alias names.

If you plan 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 to hgdownload.cse.ucsc.edu
[username: anonymous, password: your email address], then cd to the
directory goldenPath/equCab2/bigZips. To download multiple files, use
the "mget" command:
mget <filename1> <filename2> ...
- or -
mget -a (to download all the files in the directory)
Alternate methods to ftp access.
Using an rsync command to download the entire directory:
rsync -avzP rsync://hgdownload.cse.ucsc.edu/goldenPath/equCab2/bigZips/ .
For a single file, e.g. chromFa.tar.gz
rsync -avzP
rsync://hgdownload.cse.ucsc.edu/goldenPath/equCab2/bigZips/chromFa.tar.gz .
Or with wget, all files:
wget --timestamping
'ftp://hgdownload.cse.ucsc.edu/goldenPath/equCab2/bigZips/*'
With wget, a single file:
wget --timestamping
'ftp://hgdownload.cse.ucsc.edu/goldenPath/equCab2/bigZips/chromFa.tar.gz'
-O chromFa.tar.gz
To unpack the *.tar.gz files:
tar xvzf <file>.tar.gz
To uncompress the fa.gz files:
gunzip <file>.fa.gz
------------------------------------------------------------------
The horse sequence is made freely available before scientific publication
from the Broad Institute with the following understanding:
1. The data may be freely downloaded, used in analyses, and repackaged in
databases.
2. Users are free to use the data in scientific papers analyzing particular
genes and regions if the provider of these data (The Broad Institute) is
properly acknowledged.
3. The center producing the data reserves the right to publish the initial
large-scale analyses of the data set, including large-scale identification
of regions of evolutionary conservation and large-scale genomic assembly.
Large-scale refers to regions with size on the order of a chromosome (that
is, 30 Mb or more).
4. Any redistribution of the data should carry this notice.
