This directory contains a dump of the UCSC genome annotation database for the April 5, 2002 Genbank freeze assembled by NCBI. This is updated weekly on Sundays. The .txt.gz files are the database tables in a tab-delimited format compressed with gzip. The .sql files are the MySQL commands to create the tables. 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=hg11 and click the "describe table schema" button. There is also a "view table schema" link on the configuration page for each track. All of the tables are freely usable for any purpose except for the following: softberryGene.txt and softberryPep.txt - Free for academic and nonprofit use.
