Genome Annotation Transfer Utility

Genome Annotation Transfer Utility (GATU) annotates a genome based on a very closely related reference genome. The proteins/mature peptides of the reference genome are BLASTed against the genome to be annotated in order to find the genes/mature peptides in the genome to be annotated.

Note:  The program has trouble with spliced genes!!


Getting Started

If you’re new to GATU click on the launch button (on the right) and use the Quick Start Page to learn the basics (or if you’re like us…  just start clicking!).

The VBRC also provides additional help resources for GATU:

If your system does not launch Viral Orthologous Clusters, it is probably missing Java Runtime Environment 1.7. Please see Java Web Start Setup and Java Web Start Tips for help.
