This directory contains the Mar. 2007 assembly of the platypus genome
(ornAna1, WUSTL version 5.0.1), 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.
For more information on the platypus genome, see the project website:

Files included in this directory:

ornAna1.2bit - contains the complete platypus/ornAna1 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/

ornAna1.agp.gz - Description of how the assembly was generated from
    fragments.

ornAna1.fa.gz - "Soft-masked" assembly sequence in one file.
    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.

ornAna1.fa.masked.gz - "Hard-masked" assembly sequence in one file.
    Repeats are masked by capital Ns; non-repeating sequence is shown in
    upper case.

ornAna1.fa.out.gz - RepeatMasker .out file.  RepeatMasker was run with the
    -s (sensitive) setting.  The May 17 2007 (open-3-1-8) version of
     RepeatMasker was used with the 20070717 (under development) library 
     from RepBase Update.

ornAna1.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.

ornAna1.quals.fa.gz - quality scores in fasta file format

md5sum.txt - checksums of files in this directory

mrna.fa.gz - Platypus 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.

ornAna1.chrom.sizes - Two-column tab-separated text file containing assembly
    sequence names and sizes.

ornAna1.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, then 
go to the directory goldenPath/ornAna1/bigZips. To download multiple 
files, use the "mget" command:

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

The Platypus 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.
