This directory contains a dump of the UCSC genome hgFixed 
database. The data is updated nightly. The .txt.gz files contain
the database tables in a tab-delimited format compressed with gzip.  
The .sql files contain the MySQL commands to create the tables.  

The hgFixed database contains tables with information that is not 
tied to a specific genome assembly, for example expression values 
associated with probe IDs (as opposed to genomic coordinates in 
some assembly).  Many of the tables in this database are used by 
tracks in more than one assembly's Genome Browser.

To see descriptions of the tables in hgFixed, visit the Table Browser:
  http://genome.ucsc.edu/cgi-bin/hgTables
select "All Tables" as the group, select hgFixed as the database,
and select a table.  Then click the "describe table schema" button.

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/hg16/database. To download 
multiple files, use the "mget" command:

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

All the tables in this directory are freely usable for any 
purpose except for the following:

   affy10KDetails.txt, affy120KDetails.txt, affyExps.txt, 
        affyGenoDetails.txt - See the Affymetrix, Inc. web site at
        (http://www.affymetrix.com/site/terms.affx) for the 
        terms and conditions of the use of data in the this table.
