There is an example database with GFF3 source files, a
log of the commands used to build the database, database dumps at a few
steps of building the database, and an Apollo
chado-adaptor.xml config file in the
schema SVN.
The SVN repository
that has the sample databases in it is called sample_dbs and can be
checked out following the directions on the
Subversion page. The repository is quite large
(200MB) so it will take a while to download.
