This directory contains the Drosophila yakuba 2.0 assembly from the Genome Sequencing Center at the Washington University School of Medicine, St. Louis. The annotations were generatd by UCSC and collaborators worldwide. Files are 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 used 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=droYak2 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 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/droYak2/database. To download multiple files, use the "mget" command: mget ... - or - mget -a (to download all the files in the directory) All the tables in this directory are freely usable for any purpose.
