The Visualization and Analysis
of Microbial Population Structures


VAMPS is an integrated collection of tools for researchers to visualize and analyze data for microbial population structures and distributions. For more information on the VAMPS project, visit our VAMPS Overview page.

There are two essential elements to VAMPS:

  • Visualization and Analysis - Community Visualization including heat maps and comparative pie charts, as well as diversity estimates, rarefaction curves and spreadsheet-style output provide researchers with analytical tools for assessing individual microbial populations, based on either taxonomic assignments or independently-derived operational taxonomic units (OTUs).

  • Data Ramp - Researchers who want to use the VAMPS tools with their own data can enter their sequence or taxonomy data to the VAMPS website and merge it with the existing shared datasets for individual or comparative analyses. Researchers will be given a user name and password, and their data will be visible only to registered users of their choice.

Please see our Recent Updates page for more information.


VAMPS is a project of the Josephine Bay Paul Center in Comparative Molecular Biology and Evolution of the Marine Biological Laboratory in Woods Hole, MA. The project is under the direction of Mitchell Sogin and David Mark Welch and is funded through the Alfred P. Sloan Foundation.
