Viral Orthologous Clusters

Viral Orthologous Clusters (VOCs) is an easy-to-use Java GUI used to access the VBRC genome databases. With this program, you can:

• Search and extract genome, gene and protein data from the database.

• Select data (e.g. a set of genes) and then analyze it with the other VBRC tools, e.g.
  • Generate multiple alignments with Base-By-Base
  • Create dotplots with JDotter
  • Browse complete genomes with the Viral Genome Organizer (VGO)
  • Run BLAST searches on NCBI and VBRC databases
  • Plot DNA skews with DNAGrapher
  • Create genome maps
• Compare genomes and sets of genomes, e.g.
  • find gene families represented in all poxvirus genomes (core poxvirus genes)
  • find gene families present in variola viruses, but not in cowpox or vaccinia viruses (potential virulence genes)
• Our current databases include Adenoviridae, Asfarviridae, Baculoviridae, Coronaviridae, Herpesviridae, Iridoviridae, and Poxviridae. If you would like us to add any genomes or inquire about creating a new database, please contact us using the link at the bottom of the page.

• The VBRC uses an Administrator version of VOCs to add genomes, annotate genes and classify gene families

Getting Started

If you’re new to VOCs, 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 VOCs:

• How to doc; short descriptions of certain analyses you might want to do.
• VBRC Help Book, which is our comprehensive reference manuals.
• FAQs (Frequently Asked Questions)
• Finally,  just email us a question and we’ll gladly help you out.

Troubleshooting

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.
