This directory contains a dump of the UCSC genome annotation database for
the Mar. 2007 assembly of the tetraodon genome
(tetNig2, Genoscope Tetraodon v8.0 (NCBI project 12350, CAAE01000000)).
The annotations were generated by UCSC and collaborators worldwide.

This assembly was produced by Genoscope - Centre National de Séquençage
and the Broad Institute.

For more information on the tetraodon genome, see the project website:
http://www.genoscope.cns.fr/spip/
http://www.genoscope.cns.fr/spip/Tetraodon-nigroviridis-a-fish-with.html
http://www.broadinstitute.org/annotation/tetraodon/background.html

Files included in this directory (updated nightly):

  - *.sql files:  the MySQL commands used to create the tables

  - *.txt.gz files: the database tables in a tab-delimited format
    compressed with gzip.

To see descriptions of the tables underlying Genome Browser annotation
tracks, select the table in the Table Browser:
  http://genome.ucsc.edu/cgi-bin/hgTables?db=tetNig2
and click the "describe table schema" button.  There is also a "view
table schema" link on the configuration page for each track.

---------------------------------------------------------------
If you plan to download a large file or multiple files from this 
directory, we recommend 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/tetNig2/database/. 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/tetNig2/database/ .
For a single file, e.g. gc5BaseBw.txt.gz
    rsync -avzP 
        rsync://hgdownload.cse.ucsc.edu/goldenPath/tetNig2/database/gc5BaseBw.txt.gz .

Or with wget, all files:
    wget --timestamping 
        'ftp://hgdownload.cse.ucsc.edu/goldenPath/tetNig2/database/*'
With wget, a single file: 
    wget --timestamping 
        'ftp://hgdownload.cse.ucsc.edu/goldenPath/tetNig2/database/gc5BaseBw.txt.gz' 
        -O gc5BaseBw.txt.gz

Please note that some files contents, such as this example gc5BaseBw.txt.gz,
will point to the data being hosted in another /gbdb/ location, which
refers to ftp://hgdownload.cse.ucsc.edu/gbdb/

To uncompress the *.txt.gz files:
    gunzip <table>.txt.gz
The tables can be loaded directly from the .txt.gz compressed file.
It is not necessary to uncompress them to load into a database,
as shown in the example below.

To load one of the tables directly into your local mirror database,
for example the table chromInfo:
## create table from the sql definition
$ hgsql tetNig2 < chromInfo.sql
## load data from the txt.gz file
$ zcat chromInfo.txt.gz | hgsql tetNig2 --local-infile=1 
        -e 'LOAD DATA LOCAL INFILE "/dev/stdin" INTO TABLE chromInfo;'


The Tetraodon sequence has been freely provided by Genoscope before
publication for use in the UCSC Genome Browser 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, provided that the Genoscope is properly acknowledged.
3. Genoscope reserves the right to publish the initial large-scale analyses
   of the dataset, 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 Tetraodon chromosome (that
   is, 5 Mb or more).
4. Any redistribution of the data should carry this notice.
