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.

Please note that Java has enhanced security on all web applications and is now requiring all apps to be signed by a certificate from a trusted authority. We are currently updating all of our apps to a new certificate and in the mean time are using a self-signed certificate. Any application with a self-signed certificate is blocked by default on your computer unless your Java Security Settings are set to ‘Medium’ or our URL is added to the Exception Site List. There may also a pop-up window on start up of the app where you will have to accept the risks regarding the certificate. Please bear with us as we fix this!

For instructions on how to add our URL to the Exception Site List and more information regarding the new security settings look here:

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!).

If your system does not launch Viral Orthologous Clusters, it is probably missing Java Runtime Environment 1.5. Please see Java Web Start Setup and Java Web Start Tips for help.
