1. What's the IV Sequence Distribution Tool (IVDT)?
IVDT draws maps indicating the origin and quantity of our database entries within a given area. It displays the worldwide geographic distribution of the IV data so as to couple sequence data with geographical information and supplement them with contextual information of biological and epidemiological data. The map is a useful visual aid to locate a certain species and to study the IV distribution, transmission and evolution.
