All tools are accessible as Apps in the CyVerse Discovery Environment (formerly iPlant). The CyVerse Cyberinfrastructure is a freely available resource for computation, storage, and data analysis for the life sciences. We plan to extend the list of tools for viruses pending funding.  The are also general Apps for metagenomics and microbial ecology available through the iMicrobe Project.

Clicking on tools will take you to the App on CyVerse!
