This directory contains the Jan. 2007 assembly of the C. elegans genome
(UCSC version ce4, Wormbase version WS170) as well as repeat annotations and
GenBank sequence.
This assembly was produced by Washington University in St. Louis (WUSTL) School
of Medicine Genome Sequencing Center and the Sanger Institute. For more
information on the C. elegans genome, see the WUSTL project website at
http://genome.wustl.edu/genome.cgi?GENOME=Caenorhabditis+elegans.
The sequence data may also be downloaded from:
ftp://ftp.sanger.ac.uk/pub/wormbase/WS170/CHROMOSOMES/.
Files included in this directory:
ce4.2bit - contains the complete C. elegans/ce4 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. The main assembly is found in the chrN.fa
files, where N is the name of the chromosome. The chrN_random.fa
artificial chromosome files contain clones that are not yet finished
or cannot be placed with certainty at a specific place on that chromosome.
The chrUn artifical chromosome contains clones that are not yet finished,
and can not be oriented or assigned to any chromosome.
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.
RepeatMasker version: October 6, 2006 (open-3-1-6)
with RepBase libraries: RepBase Update 20061006.
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 - C. elegans ESTs in GenBank. This sequence data is updated once a
week via automatic GenBank updates.
md5sum.txt - checksums of files in this directory
mrna.fa.gz - C. elegans mRNA from GenBank. This sequence data is updated
once a week via automatic GenBank updates.
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.
ce4.chrom.sizes - Two-column tab-separated text file containing assembly
sequence names and sizes.
------------------------------------------------------------------
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, then
go to the directory goldenPath/ce4/bigZips. To download multiple
files, use the "mget" command:
mget <filename1> <filename2> ...
- or -
mget -a (to download all the files in the directory)
------------------------------------------------------------------
The C. elegans sequence is made freely available to the community by the
Genome Sequencing Center at the WUSTL School of Medicine. Please see the
WUSTL data use policy at http://genome.wustl.edu/data.cgi for data use
restrictions and citation information.
