Using blastn for annotation is an extremely messy solution. It's very
unlikely that you will identify complete genes this way - they would
need to be almost identical and the starts/stops would have to align.
You should use an ORF finding package such as Critica or Glimmer. I
believe there are Bioperl modules to deal with Glimmer output too. Mail
me if you need more help with this.
