Gbgff

FlyBase gene models displayed as remote tracks on Gbrowse, via gbgff

• gbgff is a GFF3 dumper script that come packaged with GBrowse version 1.69 and later.
• Its purpose is the export configured annotations from one instance of Gbrowse to another
• It is analogous to DAS, except that:
  • It supports both server and client-side configuration of glyph rendering
  • It supports 3-level gene models and other multi-level features made possible by GFF3

Installation

• gbgff does not require an special set-up, it is installed with Gbrowse.
• This application has only been tested with servers using a GFF-3 back-end with Bio::SeqFeature::Store
