Repeat feature annotation
If repeat data is present in INSDC when a genome is loaded, then those features are imported into Ensembl Genomes. For bacterial genomes, this is currently the only source of repeat data. For other divisions, a computational pipeline is additionally run, to annotate three types of repeat:
Annotating repeats with RepeatMasker requires a repeat library. In most cases, a species-specific library is not available, so the RepBase  database of eukaryotic repetitive elements is used. Species-specific repeat libraries from the following sources are used where possible:
Viewing and accessing repeat features
By default, repeat features are not displayed in the genome browser; display them by using the Configure this page option. You can view all repeats, or a subset of repeats based on type.
