This directory contains the Feb. 2004 assembly of the chicken
genome (galGal2, Feb. 2004) from the Genome Sequencing Center
at Washington University in St. Louis. 

Files included in this directory:

galGal2.2bit - contains the complete chicken/galGal2 genome sequence
    in the 2bit file format.  While we are providing the .2bit for
    this assembly, we will continue to use the .nib files in
    the Genome Browser.  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:

chromAgp.zip - Description of how the assembly was generated from
     fragments, unpacking to one file per chromosome.  

chromFa.zip - 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.  RepeatMasker January 2004 version with
    RepBase libraries: RepBase Update 8.4, RM database version
    20040225

chromFaMasked.zip - The assembly sequence in one file per 
    chromosome. Repeats are masked by capital Ns; non-repeating 
    sequence is shown in upper case.  

chromOut.zip - RepeatMasker .out file for chromosomes. These were 
    created by RepeatMasker at the -s sensitive setting.

chromTrf.zip - Tandem Repeats Finder locations, filtered to keep repeats 
    with period less than or equal to 12, and translated into one 
    .bed file per chromosomes.  

est.fa.gz - Chicken 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 - Chicken 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.

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.

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/galGal2/bigZips. To download multiple 
files, use the "mget" command:

    mget <filename1> <filename2> ...
    - or -
    mget -a (to download all the files in the directory)

The chicken sequence is made freely available before scientific 
publication 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 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.
