  OVERWRITE_DB = 1
  TRUNCATE_SEQUENCE_TABLES = 1

• If OVERWRITE_DB is set to 1, running this script will cause any existing database with the same [DATABASE_CORE] NAME to be dropped and recreated before any data are imported.
• Setting TRUNCATE_SEQUENCE_TABLES to 1 will truncate any existing sequence tables before importing.
• if these values are left unset, additional data will be added to an existing database/sequence table, which may have unintended consequences so proceed with caution.

[MODIFY]
  TRUNCATE_GENE_TABLES = 1

If TRUNCATE_GENE_TABLES is set, all tables that are associated with specific gene models will be truncated allowing for a fresh import of the data. Otherwise, only additional data will be imported.
