Unannotated or partially annotated sequences can be annotated against one or multiple reference chromosomes. For each annotated ORF, all possible choices are listed according to feature identity and chromosome synteny. Similar features can be clustered according to identity. The user can manually override annotations made by the software.
Chromosome annotation projects can be saved along with all information from multiple reference chromosomes and user input, and annotated chromosomes can be saved as featured sequences in the database.
