This directory contains the Feb. 2013 (WBcel235/ce11) assembly of the
    C. elegans genome (ce11, C. elegans Sequencing Consortium WBcel235),
    as well as repeat annotations and GenBank sequences.

For more information about this assembly, please note the NCBI resources:

Files included in this directory:

ce11.2bit - contains the complete C. elegans/ce11 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/

ce11.chrom.sizes - Two-column tab-separated text file containing assembly
    sequence names and sizes.

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.
    January 31 2015 (open-4-0-5) version of RepeatMasker
    RepBase library: RELEASE 20140131

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 5+
    format (one file per chromosome).

md5sum.txt - checksums of files in this directory

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 of RefSeq genes with annotated 5' UTRs.
    This file is updated weekly so it might 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.

ce11.gc5Base.wigVarStep.gz - ascii data wiggle variable step values used
                           - to construct the GC Percent track
ce11.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
ce11.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

ce11.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/ce11/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/ce11/bigZips/ .
For a single file, e.g. chromFa.tar.gz
    rsync -avzP 
        rsync://hgdownload.cse.ucsc.edu/goldenPath/ce11/bigZips/chromFa.tar.gz .

Or with wget, all files:
    wget --timestamping 
        'ftp://hgdownload.cse.ucsc.edu/goldenPath/ce11/bigZips/*'
With wget, a single file:
    wget --timestamping 
        'ftp://hgdownload.cse.ucsc.edu/goldenPath/ce11/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. elegans sequence is made freely available to the community by the
Genome Sequencing Center, Washington University School of Medicine, 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 these data
   if the providers of these data are properly acknowledged.  See
   http://genome.ucsc.edu/goldenPath/credits.html for credit information.

3. The centers producing the data reserve 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.
