This directory contains the Feb. 2008 assembly of the C. brenneri genome
(UCSC version caePb2, WUSTL version 6.0.1) as well as repeat annotations
and GenBank sequences.
Various strains of this Caenorhabditis are named Caenorhabditis n. sp. 4.
PB2801, LKC28, CB5161, SB129, SB280.
This assembly was produced by the Genome Sequencing Center at
the Washington University School of Medicine in St. Louis (WUSTL).
For more information on the C. brenneri genome, see the project website:
http://genome.wustl.edu/genome.cgi?GENOME=Caenorhabditis%20brenneri.
Files included in this directory:
caePb2.2bit - contains the complete C. brenneri/caePb2 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 WindowMasker 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.
Not available: chromOut.tar.gz - there is no repeat masker data for this
genome. In place of repeat masker, there is the WindowMasker output:
chromWMSdust.bed.gz - bed file for chrUn used as repeat areas
identified by WindowMasker with the -sdust option.
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. brenneri 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. brenneri 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.
caePb2.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
[username: anonymous, password: your email address], then cd to the
directory goldenPath/caePb2/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/caePb2/bigZips/ .
For a single file, e.g. chromFa.tar.gz
rsync -avzP
rsync://hgdownload.cse.ucsc.edu/goldenPath/caePb2/bigZips/chromFa.tar.gz .
Or with wget, all files:
wget --timestamping
'ftp://hgdownload.cse.ucsc.edu/goldenPath/caePb2/bigZips/*'
With wget, a single file:
wget --timestamping
'ftp://hgdownload.cse.ucsc.edu/goldenPath/caePb2/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 C. brenneri 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
