This directory contains the Nov. 2010 (C. brenneri 6.0.1b/caePb3) assembly
of the C. brenneri genome (caePb3, The Caenorhabditis brenneri Sequencing
and Analysis Consortium (GCA_000143925.2)), as well as repeat
annotations and GenBank sequences.

This assembly was produced by the Genome Sequencing Center at the Washington
University School of Medicine in St. Louis.

This UCSC sequence was obtained from:

ftp://ftp.ncbi.nlm.nih.gov/genbank/genomes/Eukaryotes/invertebrates/Caenorhabditis_brenneri/C_brenneri-6.0.1b/

Files included in this directory:

caePb3.2bit - contains the complete C. brenneri/caePb3 genome sequence
    in the 2bit file format.  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.  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/

caePb3.agp.gz - Description of how the assembly was generated from
    fragments.

caePb3.fa.gz - "Soft-masked" assembly sequence in one file.
    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.

caePb3.fa.masked.gz - "Hard-masked" assembly sequence in one file.
    Repeats are masked by capital Ns; non-repeating sequence is shown in
    upper case.

caePb3.fa.out.gz - RepeatMasker .out file.  RepeatMasker was run with the
    -s (sensitive) setting.  *NOTE: the genome was masked with WindowMasker
    and Tandem Repeats Finder.
    RepeatMasker version:
       June 30 2010 (open-3-2-9) version of RepeatMasker
       CC   RELEASE 20090604

chromWMSdust.bed.gz - bed file for the repeat areas
        identified by WindowMasker with the -sdust option.

caePb3.trf.bed.gz - Tandem Repeats Finder locations, filtered to keep repeats
    with period less than or equal to 12, and translated into UCSC's BED
    format.

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.

caePb3.chrom.sizes - Two-column tab-separated text file containing assembly
    sequence names and sizes.

caePb3.gc5Base.wigVarStep.gz - ascii data wiggle variable step values used
                           - to construct the GC Percent track
caePb3.gc5Base.wig.gz - wiggle database table for the GC Percent track
                    - this is an older standard alternative to the current
                    - bigWig format of the track, sometimes usefull for analysis
caePb3.gc5Base.wib    - binary data to correspond with the gc5Base.wig file
    see also:  http://genome.ucsc.edu/goldenPath/help/wiggle.html
    and  http://genomewiki.ucsc.edu/index.php/Using_hgWiggle_without_a_database
         for a discussion of how to use the wig.gz and .wib files for
         interaction with the GC percent data values

caePb3.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/caePb3/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/caePb3/bigZips/ .
For a single file, e.g. chromFa.tar.gz
    rsync -avzP 
        rsync://hgdownload.cse.ucsc.edu/goldenPath/caePb3/bigZips/chromFa.tar.gz .

Or with wget, all files:
    wget --timestamping 
        'ftp://hgdownload.cse.ucsc.edu/goldenPath/caePb3/bigZips/*'
With wget, a single file:
    wget --timestamping 
        'ftp://hgdownload.cse.ucsc.edu/goldenPath/caePb3/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
